I don't think you need rules. But I wouldn't dream of letting a player run a character without looking over the character closely. This hasn't always avoided all problems, but it does let me make sure the character makes some kind of sense for the campaign premise. And I also insist on all the players sitting down together to discuss character concepts before building their characters. So everyone should know what kind of character everyone else is playing, from the outset. I don't know how much of that you do, but if you don't, it might help avoid some of the problems you describe.
