But of course, you'd need infinite energy to go faster than light, so...
That won't work. There's no theory that allows FTL travel. If you could travel near the speed of light, time slows down considerably for you, but then there's that mass thing; you become infinitely massive. Even if possible, it only allows you to "travel" into the future. Time slows down for you but not for the rest of the universe, so when you drop back to normal speed, it's been like a thousand years and you still look 25.
I think on a philosophical level traveling back in time would be a disaster. You could possibly fix one mistake but in the process you would likely cause a dozen worse outcomes. And would you even remember the mistake you fixed? Paradoxes are no fun.
A paradox can be paradoctored.
