If you’re asking why did Shisui kill the kids Apothecary Diaries manga, the short answer is: she poisoned them as a tragic mercy and tactical choice to spare those children from far worse suffering and exploitation after their clan’s rebellion failed. The scene is brutal and morally complex; the act was intended to prevent the children from being tortured, used as leverage, or subjected to public execution, but it also haunts survivors and forces characters like Maomao to confront the high human cost of palace intrigue.
The immediate context: what actually happened

In the relevant arc, members of the Shi (or related) clan plot rebellion and schemes that put many people, including children associated with that faction, at risk. When defeat becomes inevitable, key characters decide how to handle the likely reprisals from the court. Shisui (and related actors like Loulan/Suirei in some versions of the narrative) administer a substance to several children that results in peaceful death or deep unconsciousness, presented as “medicine” mixed into a sweetened drink. The goal was to prevent those children from being tortured, used as political pawns, or executed in cruel public ways.
This moment is portrayed as both pragmatic and heart-wrenching: it spares immediate physical agony but triggers profound moral consequences for the characters involved. Readers and viewers are left to wrestle with whether the act, however merciful its intent, was justified.
Why Shisui (and allies) chose this option, the motivations

There are several overlapping reasons behind the decision:
- Fear of brutal retribution. In the palace context, rebellion is punished harshly, and the innocent relatives of rebels are often not spared. The children faced likely torture, sexual violence, or gruesome executions as examples to others. Killing them quickly and painlessly was seen by some as a kinder alternative.
 - Preventing political exploitation. Children of disgraced clans can be used as bargaining chips, hostages, or propaganda tools. Eliminating that possibility removes the chance that they’ll be paraded, used to blackmail, or placed in lifelong servitude or abuse.
 - A personal, emotional calculus. For characters like Shisui and Loulan, who had complex loyalties and affection for certain children, the choice can be framed as a painful act out of love, choosing a short, controlled end over prolonged suffering. Fans and some characters interpret it as a “mercy killing” rooted in desperation.
 - Tactical cruelty to stop a spark. Some in the palace believe leaving surviving members can lead to future insurrections. In cold strategic terms, wiping the ember prevents a larger conflagration, though this is ethically grim. Discussion threads reflect this view as part of what drove the decision.
 
These motives often overlap; the decision isn’t framed as purely one thing but as a confluence of fear, love, and cold calculation.
The moral complexity: Mercy, murder, or both?

This is the heart of why the scene lands so hard. The story deliberately blurs easy moral categories:
- Mercy argument: The way the poison/“medicine” is administered, usually quietly, lovingly, in a way meant to be painless, suggests an intention to spare suffering. Supporters of this reading argue that Shisui acted out of compassion under impossible circumstances.
 - Murder argument: Others emphasize consent and agency. The children did not choose death, and the act eliminates any chance for justice, rehabilitation, or future redemption. From this standpoint, the act is morally indefensible even if motivated by kindness. Discussion posts and fan debates frequently return to this point.
 
The narrative uses this ambiguity to deepen character development: Maomao’s reaction, for example, is shock layered with analytical understanding; she recognizes the logic but is emotionally devastated. The text invites readers to hold both grief and intellectual empathy simultaneously.
How the Act Reshapes Character Arcs and Palace Politics
The shocking event at the heart of The Apothecary Diaries, the moment Shisui poisons the children, isn’t just a narrative twist; it’s a turning point that alters both the character dynamics and the political balance within the palace. Understanding how this act ripples through the story gives deeper context to the question, “Why did Shisui kill the kids Apothecary Diaries?”
1. Shisui’s Transformation: From Victim to Moral Catalyst
Before the incident, Shisui (also known as Loulan) is portrayed as a quiet, obedient figure trapped in the rigid confines of palace hierarchy. Her decision to “kill” the children, though motivated by desperation and compassion twisted by circumstance, redefines her completely.
She ceases to be a mere pawn of the Shi Clan and becomes an active moral force challenging the cruelty of imperial systems.
Her act is both a rebellion against the corruption of noble bloodlines and a tragic assertion of agency in a world that silences women and servants alike. Through her actions, the audience begins to question the blurred boundary between justice and survival.
2. Maomao’s Emotional and Ethical Growth
For Maomao, the palace’s apothecary and moral center of the series, the revelation shakes her to the core. She has always viewed poison and medicine as tools, neutral instruments in the hands of human intent.
But Shisui’s “murder” of the children forces her to confront the emotional dimension of ethics.
She begins to see that logic and compassion often collide in environments ruled by secrecy and power. The event pushes her beyond clinical detachment and into a realm of moral empathy, something that defines her later choices in both palace intrigue and personal relationships.
3. The Palace Power Shift: Fear, Control, and Image
From a political standpoint, the “child deaths” create immediate chaos.
The Shi Clan, already under suspicion, faces internal collapse. Rival clans use the scandal to manipulate imperial opinion, while higher-ranking nobles exploit it to strengthen the Emperor’s control.
In a society where appearances dictate survival, the “incident” becomes a symbolic lesson in loyalty and betrayal. The fact that the truth, the resurrection of the children, is concealed shows how much the palace values narrative control over justice.
4. Moral Tension Between Compassion and Power
The act deepens the philosophical undertone of The Apothecary Diaries: that mercy within tyranny always comes at a cost.
Shisui’s decision, though morally ambiguous, reflects the story’s larger commentary on how compassion is weaponized or punished in political environments.
By risking everything to spare the children from execution, she mirrors the dual nature of kindness within cruelty, a recurring motif throughout the series.
5. A Catalyst for Future Conflicts
Even after the children are revived, the palace doesn’t return to peace. Rumors persist, alliances shift, and Maomao’s growing awareness of corruption becomes the fuel for later arcs.
The incident becomes a watershed moment that connects personal trauma to systemic critique, showing that one woman’s desperate act can expose the fragility of an entire empire.
The incident surrounding Shisui’s poisoning of the children is not merely a dark plot device, it’s a thematic cornerstone that reshapes the moral, emotional, and political framework of The Apothecary Diaries.
By exploring “Why did Shisui kill the kids Apothecary Diaries”, we uncover not only the pain of one woman’s choice but also the story’s broader message: that in a world obsessed with order and hierarchy, compassion itself can become an act of rebellion.
The methods: was it really “poison”?
The story frames the substance as a drug presented as medicine or sweetened juice. Two important clarifications:
- It’s not random poisoning for malice. The dosage and presentation suggest an attempt at painless sleep or death, not a violent poisoning meant to torture. Contemporary discussions in fan forums note that the method aimed to minimize suffering.
 - Forensic and narrative realism. Maomao’s knowledge allows readers to see the act from a technical angle; she recognizes what substances can cause peaceful loss of consciousness versus violent death, which is why the scene feels so chilling and plausible. The author uses Maomao’s forensic lens to explain what was done and why it would produce the intended result.
 
Fan reactions and ethical debate
The scene provoked intense debate online, which helps explain how the narrative functions:
- Many fans defend Shisui/Loulan as acting out of mercy in impossible circumstances, arguing that a painless death is preferable to brutal political punishment. Others condemn the act as an unacceptable violation of the children’s rights and agency. Both positions appear across forums and reviews.
 - Some reviewers note that the incident adds depth and darkness to the series, forcing readers to grapple with the ugly consequences of political power plays. Critics of the choice worry the story risks normalizing “ends justify means” logic if not handled with moral care.
 
How the author frames responsibility
The narrative does not handwave responsibility. It shows:
- Remorse and consequences for those who ordered or performed the act. Characters don’t get clean absolution; they carry psychological and social fallout.
 - Systemic critique: By foregrounding this choice, the story indicts the political system that created the “need” for such a choice. The tragedy is both personal and institutional.
 
Should we interpret this as heroic or villainous?
When analyzing Why did Shisui kill the kids Apothecary Diaries, one of the most debated questions among fans and readers is whether Shisui’s act should be viewed as heroic self-sacrifice or villainous betrayal. The ambiguity of her actions lies at the very heart of The Apothecary Diaries, where morality is never black and white, and where kindness can look cruel, while cruelty can carry compassion.
1. The Heroic Perspective: A Sacrifice Born of Compassion
From one angle, Shisui’s choice can be interpreted as a merciful act.
Faced with the brutal reality that the children were destined for execution due to palace power struggles, she took the only path she saw as merciful, a quick, painless death instead of the slow agony of political punishment.
To her, this decision wasn’t about cruelty but protection.
By “killing” them with a carefully chosen poison, she intended to save them from a fate worse than death, a theme that aligns with the recurring motif in The Apothecary Diaries: survival through sacrifice.
Moreover, Shisui’s resolve shows a rare defiance in a world where obedience defines worth. She acts on conscience rather than command, embodying a quiet form of heroism that challenges imperial cruelty. Her “crime” becomes a rebellious act of love, subverting the moral codes of her society.
2. The Villainous Interpretation: Playing God in a Broken System
However, to many others within the story (and to readers), Shisui’s decision crosses a moral line.
Her unilateral choice to take innocent lives, regardless of motive, reflects arrogance and despair disguised as righteousness. In the structured world of the palace, her act threatens the fragile balance of order, showing how even compassion can be corrupted by desperation.
Her actions can be viewed as hubris, the belief that she alone could decide who lives or dies.
This mirrors a recurring philosophical question in The Apothecary Diaries:
“Is it mercy to end suffering, or madness to believe you have the right to?”
From this perspective, Shisui becomes not a martyr, but a tragic villain, someone who tries to save others but ultimately brings chaos and guilt upon herself and those she wished to protect.
3. Maomao’s Lens: A Bridge Between Heroism and Tragedy
Through Maomao’s reaction, readers are guided toward a more nuanced interpretation.
As an apothecary grounded in logic yet sensitive to human emotion, Maomao refuses to label Shisui’s act as purely evil or good. Instead, she views it as the consequence of a broken system, where moral choices are distorted by power, class, and fear.
This neutrality invites readers to question their own moral frameworks.
Is Shisui’s act villainous simply because it defied the law, or heroic because it defied cruelty?
By refusing to moralize, The Apothecary Diaries forces us to confront the uncomfortable truth that both interpretations can coexist.
4. A Reflection of the Series’ Core Themes
Ultimately, the duality of Shisui’s act echoes the series’ central theme:
“Even poison can heal, and medicine can kill, depending on how it’s used.”
Shisui’s “poison” becomes a metaphor for this paradox. Her choice, shaped by empathy yet executed through violence, blurs the moral line between savior and sinner.
Rather than fitting neatly into heroism or villainy, her story embodies the complex humanity that defines The Apothecary Diaries.
It reminds viewers that in a world ruled by manipulation and fear, true morality isn’t about good versus evil, it’s about intention versus consequence.
FAQ: Why Did Shisui Kill the Kids in The Apothecary Diaries?
1. Who is Shisui / Loulan in The Apothecary Diaries?
Shisui (aka Loulan) is a complex character within the Shi Clan storyline. She serves as a consort / daughter figure under her mother Shenmei, but secretly works against the clan’s rebellion plot. Her dual identity plays a major role in how she handles the conflict, abuse she suffered, and the political stakes she faces.
2. Did Shisui actually kill the children, or was it something else?
Yes, Shisui (as Loulan) administered poison to several Shi-Clan children in Episode 21 of Season 2. However, this was not simply cold-blooded murder, she used a poison that mimics death, paired with or followed by a resurrection drug. In other words, the children were temporarily incapacitated or poisoned so they appeared dead, but there was an intention that they be “resurrected” or saved afterward.
3. Why did Shisui decide to poison/killing-the-children this way? What was her motive?
Her motive was desperate survival under brutal political pressure. According to analysis, she believed that if the rebellion failed, the Shi Clan children (including innocents) would be executed by imperial forces anyway. Poisoning them to “appear dead” was intended to spare them from immediate slaughter. In other words, it was (in her view) a twisted mercy, an attempt to protect them from even harsher fates.
4. Did the “resurrection drug” always work? Were the children really saved?
Yes, later in the arc it’s revealed that the resurrection medicine was used to bring the children back. But there are costs: memory loss and possible trauma as side-effects. For example, one child (Kyou-u / renamed Chou-u) wakes up but has memory issues or partial impairment.
5. How does Maomao react to Shisui’s actions?
Maomao is deeply conflicted. On one hand, she’s horrified by seeing children apparently dead. On the other, she slowly learns more about the stakes and rationale behind Shisui’s decision, that inaction could have meant worse suffering.
Her reaction mixes moral outrage, sorrow, and empathy once she understands the severity of the threat the Shi Clan faced.
6. Is Shisui / Loulan considered a villain now? Or a tragic hero?
That’s a big debate among fans. Some view her as having crossed a line, the poisoning is morally indefensible in many eyes. Others see her as a tragic hero making a brutal choice in an impossible scenario. Her character is intentionally written as morally ambiguous.
Her identity as Loulan (her secret persona) and the reveal of her true motivations complicates the idea of “villain” vs. “hero”
7. What happens afterwards to Shisui and the children?
After the rebellion arc concludes:
- The children are revived (with side-effects like memory loss or trauma).
 - Shisui fakes her death (staged demise under snow) and re-emerges under a new name as “Tamamo”
 - Her relationship with Maomao becomes deeply strained yet emotionally complex.
