So I just re-watched Thor and I started wondering how Thor is actually allowed to wield his hammer. The whole starting point for the movie is Thor taking revenge against the Frost Giants for disturbing his coronation by going to kill them all.
To me, that act of revenge and brutality would make the user of Mjolnir not worthy. Being worthy shouldn't include holding grudges and behaving out of anger.
I know that at the end of the movie he redeems himself and after that he doesn't take revenge but it still shouldn't make him worthy because of that one act surely?
