Okay, well, he'd better come back as a super-turbo-charged Voldemort-like villain and then HIS death had better be epic. No redemption arc for the guy who killed Han Solo. Ugh, I feel so cheated. I thought his story would end happily by the end of the 3rd movie. But there's no happy ending once you've killed Dad and if they try to bring him back to the light side, it's going to be hollow.
Ugh again. If they'd even had Han die accidentally while trying to save his kid's life, that would be preferable to an out-and-out murder.
