But... What if, hypothetically, something they want belongs to someone else? Then they can't take it. They have to give it back to their rightful owner, otherwise it'd just be stealin'. Heroes don't steal.

Or what if they want to run away from their responsibilities, even though lots of people are counting on 'm? See, that's what I mean with not just doin' what you want. You've gotta make the decisions that help more people than just you.
