Edit since I can’t reply: if “murderer” means someone who takes actions that have nth-order effects of someone dying, with no reasonable or discernible limit on n, then we’re all murderers and the term means nothing.
Oh wait, he didn't break any laws? Hmm...well, fuck the idea of having a legal system I guess, let's just cheer every vigilante who decides to murder people in the street based on their own feelings. I'm sure that'll work out well.

This is the same talk that saw people turn a blind eye to all the horror in history. You invent a fake story that casts someone (Jews in Nazi Germany, the middle class in Soviet Russia, whatever it is) as worthy of death, and then you do everything you can to excuse the behaviour of their murderers.
