What he wants to do sounds good, but honestly he could go either way, that and he's young, those idealistic dreams of his could go sour as he gets older. Not that it matters to our world, but if any Templars show up here it could turn out bad for us, and also I wouldn't want to set him lose on a world where nobody can keep an eye on him. On the other hand, he does want to work on the corruption in the church, and a Borgia who doesn't want to exploit everyone would be a nice change of pace.
