I jump off a high area then I get shot in the head by an inno while falling midair because "BananaCoconuts was going to die anyway"
I find this kind of the same situation as people killing each other in the water trap on 67th way. Just cause you are going to die doesn't mean you are justified killing an innocent.
Always RDM, but I normally won't anything about it unless someone reports the person (why make an issue that doesn't exist).
