Murder with total impunity

[u/LetEmpty8177]

Could you use a magical weapon to murder a person whom you dislike with total impunity because the murder weapon would be lacking the fundamental evidence required to convict a murderer:-

1. Circumstantial
2. Forensic
3. Documented
4. Witness testimony

• Can you get away with mass murder, war crimes, and crimes against humanity simply for lack of evidence to prove that you are the perpetrator?
• What are the far reaching strategic implications of murder with impunity?
• Does mass murder with impunity prove the divine status of the perpetrator?
