How to fix team killing.

I'm assuming we have all been in a situation where a team mate goes rogue in the first round killing one of your teammates, then they look at you, what do you do? Wait for them to shoot you? Or kill them? Im guessing most of us would kill them, in that case you can assume that player is going to kill you in the beginning of the next round, what do you do? Kill him, get banned, or accept death and play next round? It's a lose lose situation. There can be such a simple fix to this, allow players to kill team killers! For instance, if i kill one of my team, that should allow my team to kill me twice. This would prevent me from going rogue and getting someone banned on round two. And maybe count a team kill as a vote to kick, that way it only takes two more votes to kick the team killer. It's rare that I ever see a team killer get kicked, probably because the whole team didn't see the situation, or maybe they just don't care. Team killers have too much leverage in these situations, they have nothing to lose because obviously they don't care if they get banned. The game should never be on their side! Where is the justice! Anyways these are just a couple ideas, they may not be perfect but it's a start. Teamkilling is a huge problem and Ubisoft needs to address it ASAP!!
