A detective, Innocent (me), and Innocent Mickey successfully kill a Traitor. We establish that I am proven, and Mickey is tazed and proven.
Directly after I go on to T-Bait (Role-Unknown) Chair. After I T-Bait him, he T-Baits back, and then a second later KOS' me. I KOS him back and call out in the comms that I am proven and he is not. I kill Chair, and identify his body while communicating in the comms what happened.
Innocent Mickey comes and kills me based off of the grounds of, "an Innocent killing another Innocent is KOS". I debate him, and tell him he is wrong. Another one of his possies' arguments was," You are not allowed to KOS someone back if they had a real reason to KOS you". I tell them I was KOS'ing Chair because in my eyes he had false KOS'd me, since I knew I was proven (regardless of his basis to KOS me).
Should I have been killed, and was what I did justified? I'm only asking this question since I faced so much opposition in-game, and had an admin conflicting their opinion.
