Logic I can get behind

like suicide?

Genocide?

It must not have been THAT bad of a decision.

Could be that the person voted to come back had died before coming back. Or, they messed up building the time machine, and accidentally turned it into a cryogenic chamber.

They would've seen the wisdom in not stopping we2. It could have huge affects you might not have thought about, and its all over now and there wasn't any lasting bad outcomes except the memories, which might be gone by their time. And if u just killed Hitler or something someone else would just rise to power, and who knows what would happen. And the atom bomb wouldn't have been made either, for Better or worse.

So basically what I said lol.
