Answered GBA or not?

There are 3 players: Player A, Player B and Player C.
Player A is innocent.
Player A kills Player B while Player C is watching and does nothing about that. Is Player A allowed to kill Player C for GBA, or not? (disregarding the toxicity of the act)

 

This isn't toxic gameplay, it's simply RDM. Player A can't kill Player C for ignoring a traitorous act that Player A themselves committed.

If this was a thing, you could do things like hold a T weapon and shoot everyone that looks at you or T bait someone then kill them for not shooting you.
