I imagine a lot of people would end up like homelander. Only playing the superhero role to get likes or feel loved but being very evil when no one would know.
Personally, I think I would give the superhero thing a go as I do like helping people, but very likely I'd end up like Red Son or Injustice Superman. It would depend on the powers and if other supes exist, but it is very believable to end up going to extremes to just try and make the world a "better" place if no one could stop me. What's a few lives here or there when you believe you are saving so many more?
Giving up. Just skipping straight to the end.
Sure seems like a lot less work and stress than what I've been doing.
But I think I'd miss my dogs way too much.
