Originally posted by cdtmHonestly, if Genndy is going to acknowledge time paradoxes, both Old Jack and Ashi should have ceased existing (had Aku died in the past, Jack would never have had any of the experiences he did while in the future, including traveling back in time to stop Aku). And young Jack should either cease existing as well or wake up in a timeline where everything is normal.
But he DID get sent to the future. Aku being killed AFTER Jack is sent forward wouldn't undo that. Not any more then destroying a plane after the passengers depart would prevent their trip.It WOULD undo Aku existing in the future, though.
