So, there are those who claim that he did it to prove he was the son of god. In other words, it had nothing to do with the suffering of the people he helped, it was all self-promotion. Well, at least that's consistent with the view that some have expressed here that there's no reason to care about other people other than because god tells ya to.
Personally, I think he did it to pick up chicks.
As far as who else could do the things he did, well, hucksters on television do much the same thing every day, and for apparently similar reasons, i.e., to make people believe the things they say are true. Of course, that's completely different because the hucksters are frauds, but Jesus was the real McCoy.
