In my head, Vader relives every single moment he ever had with Padmé over and over again. Partly for comfort, partly because he misses her, but mostly to torture himself.
I wonder, if in all his remembrances, he thinks of how Palpatine admitted he knew of their marriage (Revenge of the Sith novelization by Matthew Stover), and yet he still sent Padmé on a mission to basically seduce Rush Clovis.
And I wonder if it ever crosses Vader's mind that Palpatine did this just to drive a wedge between them. That Palpatine tried to get between him and his wife.
I wonder if he ever thinks about how many times Dooku tried to have Padmé assassinated, but Dooku was just taking orders from Palpatine.
I wonder if he thinks about every risky mission Palpatine sent Padmé on, missions where she got captured or badly hurt.
Vader is not stupid.
You know he thinks about these things.
You know he hates Palpatine for all of this, and so much more.
And yet, Vader stays by Palpatine's side.
Not because he believes Palpatine is his friend. Not even because he believes Palpatine will help him become more powerful, though he definitely tells himself this lie.
Vader stays because Palpatine is the only one who accepts him. If Vader left, where would he go? What purpose would he have? He would have to go live out his life completely alone and isolated, and he would be forced to confront all the grief and the horror he caused.
Nobody loves Vader, nobody ever could.
He hates himself.
Because he was the Chosen One, who couldn't save his mother, who couldn't save Ahsoka, who couldn't save his wife, who couldn't save his unborn child.
And this existence, of being used and made to do all these terrible things, is what he deserves.
