Or maybe it's because she's the villain, and she wants to destroy existence, and that's the end of that. It doesn't need to be any more complicated then necessary.


Would it not make more sense if someone on the future wanna to take over his/her own world which is more advanced than the one on the past or even take over an era further than his/her?

At least it makes more sense than a person trying to make a crazy time soap denying existence to rule it all.
This last one sounds too Nirvana like.

This is were my theories start to make more sense than yours.
