In Undertale, the player’s choices significantly influence the game’s narrative and overall tone, especially regarding the decision to “kill” versus “spare” monsters. This dichotomy manifests most starkly in the Genocide Route, where the protagonist systematically eliminates every monster in the Underground. The consequences of these choices not only shape the player’s experience but also engage deeply with themes of morality, consequence, and the nature of violence in video games.

Key Effects of Killing Monsters

1. Dialogue Changes: One of the most immediate effects of choosing to kill monsters is the alteration of character dialogue. NPCs begin to react to the player’s violent actions with a range of emotions from fear to hostility. Characters who would typically engage in light-hearted banter or offer assistance become suspicious or aggressive. This shift reinforces the world’s perception of the player as a threat and contributes to a more oppressive atmosphere, contrasting sharply with the interactions in the Neutral and True Pacifist routes.

2. Emotional and Narrative Consequences: The narrative tone becomes significantly darker as the player progresses down the Genocide Route. Each kill weighs on the story, culminating in a profound exploration of the moral implications of violence. Emotional moments, especially after taking down significant characters or bosses, evoke feelings of sadness and regret, challenging players to confront the impact of their choices. The game cleverly mirrors traditional RPG mechanics, where violence often goes unchallenged, prompting a reflection on the nature of player agency.

3. Game and Story Branching: The distinct pathways presented by Undertale promote diverse gameplay experiences based on the player’s moral choices. The three main routes—Neutral, True Pacifist, and Genocide—unfold unique dialogue, events, and endings. Particularly in the Genocide Route, encounters and boss fights shift dramatically, with characters delivering modified dialogue that reflects the weight of the player’s aggressive intent. This branching structure encourages players to navigate the narrative with awareness of the broader consequences of their actions.

4. Example Effects on Characters: Specific characters exhibit unique responses that highlight the emotional stakes of the Genocide Route. Notable characters like Papyrus provide illustrative examples; their reactions can pivot based on whether players choose to spare or attack them. Sparing certain characters might even abort a Genocide run, illustrating the delicate balance between the player’s intent and the characters’ fates. This dynamic not only deepens character development but also showcases the game’s commitment to meaningful choices.

Conclusion

In summary, the act of killing monsters in Undertale profoundly alters the player’s experience, both in terms of the immediate gameplay and its broader narrative implications. The game’s design actively involves players in a conversation about the nature of their choices, using character dialogue and narrative shifts to reinforce the consequences of violence. By doing so, Undertale stands as a thought-provoking commentary on morality within the gaming landscape, urging players to reflect on their actions and the impact those actions have on the game world and its inhabitants. Through its unique approach to storytelling, the game powerfully challenges the conventions of traditional RPGs and invites a deeper consideration of the implications of player choice.
