Also, he was the one who killed his wife.
Upon finding out that he was the one ultimately responsible, he went “nooooo” and I suppose went “well, as long as I’m in this cool suit, guess I’ll just keep doing the evil then”.
Frankly, I find his arc to be one of the least convincing “how a guy went evil and was redeemed” in fiction. Empire strikes back had the benefit of being able to leave it vague enough to leave it a potentially interesting turn, but when they actually had to delve into it, was pretty unfulfilling
Fun space action movies, but execution on the “twists” was not the strong point.






Yeah, absolutely nothing in the writing explained why he stuck with the emperor. I feel like the last thing he would have done based on his motivation to that point is stick with palpatine. Beyond being a psychopath, it doesn’t even make sense by those standards.
Empire strikes back set up a couple of plot twists that the series really couldn’t execute on. Nice in the movie since they got to leave it open ended, but bad for the series when they actually had to run with resolving those twists.
