This and anything else you would wish to have changed... Be warned, though, avoiding something bad may not lead to a good ending after all. But that's not something you would have to deal with, either.

[It's a double-edged sword after all.]

On the other hand, it's not just one other world in which you could make sure that this particular event never happened. There's an infinite number of worlds, after all. And more and more keep being born with each second that passes in your life. One change, and millions and trillions versions of you wouldn't have to go through what you have.

It's both the reward and the price. If you're willing to take it.
