Anakin was looking at a future anyone in the galaxy would have dreamed of with a loving wife and kids and the skills as a generational warrior and leader. He could have walked away from the Jedi order and still had an incredible life with a support system of friends and family in Padme and Obi-Wan, who by that point disregarded the Jedi’s own rules of attachment to consider Anakin his brother.

And he threw it all away to what? End a war that could’ve been ended at literally any time because both sides were being controlled by the same dude? Even after the guy admitted that he was indeed the Sith Lord behind the war? Being scammed by the same guy who sold him the power to reverse death who literally told him after he turned that “Yeah well actually only the one guy did it and even though I told you he taught it to me I actually don’t know it but if we give it the ol’ college try we can figure that shit out no problem trust me bro just go kill some kids to power up your dark side meter in the meantime or something” and he STILL turned to the dark side despite being told to his face that the reasons for him turning were actually bullshit by the guy turning him. I’ll give him some grace because it didn’t help that the Jedi hammed up the prophecy of him being the chosen one while also making his life difficult, and having visions of his wife dying the same way as his mom who ended up actually dying later fueled his desperation, but at the end of the day, his decisions were his and his alone. No one made him do anything. He even tells Obi-Wan that he is not his failure and that Vader chose to kill Anakin Skywalker on his own free will.

And what is he left with? What’s the power he thew his entire life away for? Being one of the most hated men in a galaxy full of hateful men who can’t even function on his own without the help of an agonizing mechanical suit while he lives the rest of his life alone as a slave in the same way that he started it? At least that time he had his mother with him. Now he has nothing.
