What's stopping me from being a T and killing people, then claiming that they did something to me to make it justified? Should other players in the round who KOS/kill me roll the dice on whether or not I am a T that should be killed, or an innocent that had justified reasons to kill people and therefore hold a potential slay over your head if I feel maligned enough to report them?

Nothing is stopping you from doing this. It's up to the Innocents and Detectives to find evidence that you did it before killing you. This is how you play TTT. If they have no evidence and they kill you then report them for rdm.
