First off, there's no such thing as "teamkilling" because there are no teams. From what I understand, anyone can kill anyone.

Second, you start off with no resources. It would be pretty silly to play long enough to get enough resources (guns) to kill someone only to throw yourself at anyone and everyone you see, considering each attack would diminish your resources and they are likely to try pretty hard to fight back and kill you, at which point you'd have to start over.

It might be fun, but it would get tiring quickly I think
