I'm thinking of his determination to keep the armour to himself, and not let anyone but him have his weapons... perhaps 'control' might be a better way of putting it? He doesn't trust anyone but himself with them. (I think this extends to Comics Tony; it's not so much he wanted to be all those things, but he didn't think anyone else would do them better.) It's a narrow line between that and villainy, so seeing another take on it would be interesting.
