Oops, I've been watching Doctor Who/reading Homestuck this week, can you tell?

1. Assume you can have any superpower you wish. What would you choose, and why?
2. Assume you have the capability to time travel. What are your opinions on causing potential time paradoxes and how would you attempt to avoid them?
3. This is probably a cliche question, but an important one nonetheless. If you did have any superpower you could, would you use it for good or evil?
Well, technically my answer consists of a reply to two of the above questions. I would certainly choose time travel as a superpower. Think of the many possibilities! Traveling back in time to witness certain events occurring would be amazing! Perhaps, in some cases, I might find myself in a situation where my coming back to that point in time would be wholly necessary, and NOT going back to that point would mean that history would have turned out entirely differently. In that case, not going back in time would mean that the current reality would have ceased to exist, as I would have failed to create a stable time loop in any way. But I don't think I've explained fully why I want to be able to time travel. After a heavy bout of watching various characters of various shows adventure in time this weekend, I have to say, what they're doing seems fun. But at the same time, I've seen the various risks inherent in doing so. The toll on one's mental faculties in particular. Even after having seen the risks, though, I think time traveling would be worth it. The experience of traveling anywhere I want, at any time I want, is greater than I could deny. Being able to witness various historical events is something I would love to do. And honestly, if power such as that needed in the case of a stable time loop was put in my hands, I wouldn't hesitate to do what i had to do to make sure that history turned out right.
