I think what makes Tyrion so great is that he's above all the petty squabbles over power that everyone else is so invested in because he knows the fact that he's a dwarf means he'll never be a leader, ironically this means he'd probably make the best leader if that could happen
“The larger the group, the more toxic, the more of your beauty as an individual you have to surrender for the sake of group thought. And when you suspend your individual beauty you also give up a lot of your humanity. You will do things in the name of a group that you would never do on your own. Injuring, hurting, killing, drinking are all part of it, because you've lost your identity, because you now owe your allegiance to this thing that's bigger than you are and that controls you.” - George Carlin
