*scratches head*
I'm trying to fully understand what you're saying here.
so the light side of the Force and dark side arent the same Force? the Force knows if its good or bad and good Force wont be in a bad person?
So when Anakin 'died' in ROTS he didnt die but all the good Force was like "ok guys, he's gone bad, lets pack our bags and get out of here" (baby midiclorian) "do i need to take everything?" (mama midiclorian) "no, he'll be good again and we can return, just take what you need for about 25 years, and we'll just float around his head until then"
so then, when he redeems himself all the bad Force leaves and the good Force comes back? So there wasnt still good in him, there was good 'around' him. Guess its one of those point of view things.
the point you're (and anyone else that fails to see the problem with Hayden as the Force ghost) is that if he died at that point then he was never Anakin after he turned to Vader. When he redeemed himself he would have become Anakin again, so taking the death point of view he had to have been reborn. either way, Since Vader (Anakin) was undeniably good at the end, telling Luke he was right (right about 'There is still good in you') he would have become Anakin again, since he died shortly after, the last form Anakin would have been in would be the old/aged Anakin we see under the mask.
as a slight aside, if you wonder why in the Original he wasnt burnt and armless as a ghost its because the ghost shown was basically the old Anakin with all his wonds healed/removed. Like in Happy gilmore when Happy see's Chubb in his dream and he has his hand back.
