Firstly you should post this in his feedback thread:
http://forum.melee.org/game-admin-feedback/%28eu%29-fin/Secondly, In the first screen where he kills me (Juta) it is clearly at the end of the round. You can see the flag being raised in the background. Me and him were just hitting eachother, it had 0 effect on the outcome of the round which ended about 1 second after that tk.
On the last screen, where I am also present. Fin isn't doing anything wrong either, he is attacking enemies with his throwing axes. Me and the other 2 guys had taken a hostage and were holding him prisoner, nothing wrong there. Just some good role play, we killed him shortly after.
On the rest of the screens I wasn't present, so someone can answer instead.
As for the 'troll clan' comment:
