Assist kill jokes

If you kill an emo, Is it an assist kill?

I was playing Warzone last night, and I shot my teammate that said they were emo. When I shot him, another player did, and it said "assist kill."

Two kids were beating up a kid in an alley, so I stepped in to help. He didn’t stand a chance against the three of us.

They say there's a person capable of murder in every friendship group. I suspected it was Dave, so I killed him before he could cause any harm.

I don't call it suicide. I call it population control.

You call it a tragedy. I call it a 25 killstreak.

If a person shoots a person about to commit suicide, is it making it less painful, or is it murder?
