Darth Vader was the ultimate deadbeat dad. Angry, abusing the mother, and he didn’t even know he had kids because he’d stormed off to take a promotion at the job which consumed his life. Then decades later, when the job is going badly and he still hates his boss and he’s not half the man he used to be, he suddenly starts trying to convince total strangers who just happen to have some of the same genes that they’re totally meant to have a great life together. And even that can’t stop him being the same aggressive prick right up to that point. One which thinks the sheer amount of bullshit he’s subjected everyone too entitles him to more consideration.
Then he breaks out the ludicrously large gifts. “How about an entire galaxy, eh son? Huh? Big galaxy just for you.” And even when that fails he still ups the awkwardness ante with the excruciating embarrassing attempts to use someone who already hates him to get in touch with other siblings who literally can’t stand the sight of him. “How’s your sister, eh? Did she like that torture droid I got her?”
And the asshole still gets his happy ending. But not for his sake. Those who survived him can heal easier if they decide he turned good at the end, appreciating his final nobility but only doing while burning all evidence that the asshole ever existed. I’m surprised they don’t have a restraining order against his Force Ghost.
