A lifetime of evil-doing, including destroying a planet with billions of innocents, and he gets to be friendlyghosting with his old buddies? Just because of a single act of goodness? Noooooooooo!
Vader could have choked him to death. He would do it to subordinates who failed, he could man up. At least he should have tried to talk Tarkin out of it. He was just as guilty.
Not to mention killing children in cold blood (in the prequels). I've just seen the series in chronological order with my kids - we had lots of fun, with all its inconsistencies. That final scene is what bothered me the most. I feel it absurd for him to have happiness in the afterlife.
Tarkin wasn’t Vader’s boss, they were equals, the only time Tarkin ever gave Vader anything resembling an order was when he told him to stop choking that imperial officer, other than that they were equals. Tarkin even refers to Vader as “my friend” later on and Vader openly defies him and talks back to him.
Vader also killed children and his old friends at the Jedi Temple on Coruscant, as well as lead the charge during the Great Jedi Purge set between III and IV. He had a lot to answer for indeed.
Padme knew he killed women and children sandpeople and she still married him. Sandpeople are not animals, they are sentient beings. Instead of reporting to the Jedi Order, she keeps quiet about it--shameful this is.
According to some religions, you can get away with all that shit and more, if you just repent at the end. Which is only one reason I'm not too keen on those religions, some acts are and should be unforgiveable.
Which brings us to the question of Darth Emo in the new films. He's the last of the Skywalker dynasty, yet he's slaughtered innocents and deliberately devoted himself to a career in unforgivablity, and that gives us a big problem in how to wrap up the current trilogy. Does Rey kill him and remove the evil from the galaxy, and thereby extinguish the Skywalkers? Does he get forgiven for the unforgivable, which I wouldn't like one bit?
Sadly, the only way I would accept his redemption is no longer possible - if his little tiny mother had bitch-slapped him into groveling submission I might be satisfied with that because that's the greatest humiliation a man can suffer and live, but that can't happen. I suppose the only possible route left is to die a redemptive death and leave Rey pregnant with a new Skywalker, and I don't like that idea very much. Not many good options left.
If Anakin really was a child of prophesy meant to bring balance to the Force, all that horrible crap he did was just the Force taking out its own trash. He's not a bad guy at all. Age old argument. Was Hitler really a bad guy if our paths are predetermined and there is no free will?
