This is Superman:Cap. How was he "evil" at any point in the movie? He was a young and conflicted Superman learning his powers/abilities and also trying to find his place in the world. He had never even been in a real confrontation yet..
All through that he is doing good around the world.. saving humans.. the guys on the oil rig etc.
He eventually finds his place and decides to stay and improve the world anyway he can. That's after he nearly dies protecting people who didn't want him there.
it's a little more grounded that a typical boy scout story arc from the 50s or 60s but it's in every way.... Superman. You lost.
You LAWST!
