Bart
The fact that you exist in multiple worlds, Bart, says that you have a much greater destiny than just dying young. Think about that. The multiverse keeps creating you because you are needed.
And yes, doing good is a thankless, harsh, punishing job. But when you stop, you realize that the alternative, doing nothing at all, is so much worse. I don't want you to come to a point where you lost someone dear because you stayed still instead of doing all that you could. It is a soul-crushing feeling.
