I need help on this one.

I've been playing hardcore for around 4 months now ever sence Treyarch did their famous Gun Patch's and made the game horrible again.

So, so many times i've been 1 kill away from Vsats, Swarms, K9 Units, EMP Systems ect and team mates kill me..

I don't see what the posotive outcome of this is, yeah you're going to make the person rage, but at the same time you're slapping yourself in the face, with the Orbital Visats that i carry my team with, they could get so many more kills and killstreaks with having the clear advantage, Assult killstreaks such as K9 Units, Swarms, Lodestars ect push the enemy back into the spawn to prevent them spawning all over the map and causing your team mates to die, swarms also give alot of help towards your killstreaks, If you put a UAV up in the air whilst a friendly swarm is out you can sit there and watch your killstreaks roll in.

But still yet near enough every lobby i get into i get team killed around 2-5 times a game, mostly off high killstreaks which would be supporting the team helping them win the game and helping them gain more kills..

but still yet, i go into a game of Hardcore Domination, Kill confirmed, Team deathmatch and i see team mates spawn in and just spray at team mates, get themselves kicked, get themselves probation and do nothing but punish themselves for the action they've taken.

Someone PLEASE explain to me why people feel the need to kill team mates when CoD is a team-based game.
