Well, that really depends, because I'd have no idea of the ramifications of my actions on the whole, rather than just the measly little scope I could process on, which would be the whole part. Although, I started a rant about this once upon a time, back before I even joined the Escapist, so I may have a strangely long-winded concept of food-for-thought, which I will try to illustrate on the barest of minimums here.
The largest issue is that I don't think I could convince myself, much less anyone else, what I was doing wasn't blatant abuse of ability. Should I ever have the power, who's to say I'd be right to use it selfishly? I could do things to prevent thousands of death on September 11th of 2001, or even go into the recent past and prevent American and British tourists from being trapped in a terrorist-hostage situation. Go further back, maybe even prevent the Holocaust, or historical massacres. In doing so, how criminally badly would I change history, or even my own life should I change something small. But I'd have no way of knowing if it was for the better, or for the worse.
In short, no, I'm fairly sure I wouldn't. My life hasn't been all sunshine and pixies, but it's certainly nothing approaching a tragic life. I was born with my entire body working, no terminal maladies or lifelong mutations. Now, most of what I have makes me define my life as a good one, despite occasional irritations.
