It's worse than being Superman and doing nothing, it would be as if Superman's powers were leeched off of other people, depriving them of their health/well being/life expectancy. Then, he only saves a select few whenever he has a whim. He could just give the power back to each person.
Edit to avoid double-post: @Josh I wish I could "unlike" that Pogo video. I had forgotten about Pogo/Nick Bertke since his initial Disney stuff. In looking into his work after you posted that video, I learned that his a huge misogynist, anti-feminist, and a Trump supporter. F*** him. I'm out.
