I haven't watched the Avengers so I can't comment on Ultron, but I've read my fair amount of Norse mythology so here it goes:

Loki is the "god" of mischief and chaos. He doesn't really need a motive behind his actions. Although I have to bring up that in a lot of his stories, he does stuff to undermind his father, Odin, and the other gods (especially his brother). So yeah, there's that.
