Should I Kill Silus Vesuius?

When It Makes Sense

• Good fit: You want Mehrunes’ Razor for your build or collection. Killing Silus is typically the path that lets you reforge the Razor and claim the Daedric dagger at the end of the quest.
• Good fit: You are roleplaying a power-hungry, Daedric-aligned, or morally flexible character. If your Dragonborn serves Mehrunes Dagon or values strength over mercy, killing Silus is consistent with that arc.

When You Should Avoid It

• Warning sign: You are playing a heroic or merciful character. Silus is not hostile when you first meet him, and killing him at the shrine is an execution-style choice that may conflict with a good-aligned playthrough.
• Warning sign: You prefer to keep NPCs alive for immersion, future interactions, or a “no-kill” run. Sparing Silus preserves him as a living character and may feel more satisfying if you avoid unnecessary deaths.

Pros and Cons

Pros

• You can obtain Mehrunes’ Razor, a unique Daedric dagger with a low-chance instant-kill enchantment, useful for stealth or one-handed builds.
• Killing Silus completes the quest in the way Mehrunes Dagon demands, which fits a Daedric-prince-aligned narrative and counts toward the Daedric artifact achievements or trophies.

Cons

• You lose the roleplay option of showing mercy, which can feel out of character for paladin-style, heroic, or compassionate Dragonborns.
• Silus dies and is removed from the game world, so you cannot later revisit his museum interactions or any potential future content tied to his survival.

Decision Checklist

• Do I need Mehrunes’ Razor for my current build, achievement progress, or Daedric artifact collection?
• Does my character’s morality align with executing an unarmed NPC, or would sparing him make more sense?
• Am I comfortable reloading a save to see both outcomes, or do I want to commit to one canonical choice?

Alternatives to Consider

If you are unsure, the easiest alternative is to save the game right before the shrine confrontation and try both choices. Sparing Silus lets you experience the merciful outcome, while killing him unlocks the artifact. On PC, you can also use console commands or mods to obtain Mehrunes’ Razor without killing him if you prefer a non-lethal path. For players focused on trophies, remember that you may need the Daedric artifact associated with this quest for the “Oblivion Walker” achievement.

Final Recommendation

Kill Silus Vesuius if your priority is obtaining Mehrunes’ Razor, completing the Daedric questline, or roleplaying a ruthless character. Spare him if you are playing a hero, value NPC survival, or simply prefer the merciful outcome. Because this is a single-player game choice with no real-world consequences, the best answer is the one that fits your character and goals. If you want both outcomes, save before the decision and reload to compare them.
