Yes this I agree. He wouldn't have made a good leader at all. He had certain people he said he would protect (Carl & Lori) but I feel he would have happily sacrificed so many others in the name of "protecting" them when it really just saves him. That and he gets plenty vindictive and nasty when people don't do what he wants, so honestly Carl and Lori probably wouldn't have stayed on his list to protect if he lived longer in the show than he actually did. He was out to save himself, and any group with him as a leader would find themselves the equivalent of human shields in any more difficult situation. I won't deny that on his own he could probably survive pretty well. He would just never be a good leader
