what character development ? I thought that what made Joker such a nice character was that he lacks character completely, he just "do" things like he says

he's more like a force of nature, an "agent of chaos", that made him completely unpredictable and dangerous. But why does he do what he does? what's his motivation besides just a nice challenge? I didn't see any of that in that movie.
