Theory Briefing
- Undertale lets players spare or kill every enemy, turning each encounter into a live ethics experiment about consequentialism vs. deontology.
- The game's 'Genocide' and 'Pacifist' routes produce radically different endings, illustrating how repeated choices shape identity — a nod to virtue ethics.
- Fan theorists dissect Undertale's lore obsessively, showing how ambiguous narratives fuel parasocial engagement and collective sensemaking communities.
