>>103822943They should have had the climax of the series focused on Jack contemplating between leaving for the past and staying in the future. And having Jack mournfully accept that the past is gone, and everything evil Aku did already happened. Suggering and death was inevitable. His parents lived the rest of their lives longing for him, sure, but he was gone, and they eventually accepted it. And instead, by existing in the future, he banished the master of all evil in a point the earth needed it the most.
By going back, not only he forsook all of his achievements and lost the love of his life. Also, if there's a profecy he was destined to defeat Aku, it would most likely be ambiguous about "when" Aku is supposed to be destroyed. And perhaps Jack was supposed to deafeat him in the future and remain there to ensure his banishment for good, instead of leaving a world that the demon master had a long time to taint and spread his seed, so to speak, as with Ashi.
Really activates the almonds.
