1. I think mainly hero, but it depends largely on my mood. Maybe I'd go totally darth vader/ Thanos/ reaper and set out to destroy the most advanced species who are destroying their planets. So it depends on the setting and my mood. My current mood is villian.
2. Disney Film: Lion King but if it is also none disney then it is Spirit. What I like the least about them *thinks really hard* I don't know, I love everything about them, guess that is why they are my favourite movies
4. Billionaire, not because of the money but because I don't want to be immortal. That sucks. Especially when you go for true immortality where nothing can kill you and you keep on existing even after the sun has blown up the planet.
5. Save the ecosystem. Humans can suck it.
6. Yes. You should make sure that it is a life threatening issue. Sacrifice one to save millions? Yes. I mean any person who either had to sacrifice themselves or save millions of people said I don't want to do it, isn't worth having around anyway.
If it is a smaller issue it really depends. I can't think of a good example right now.
7. Not at all
