Slaughtering a room full of children would be an automatic disqualifier for the title of “the greatest Jedi ever”.
Or butchering an entire village years earlier: “I killed them. I killed them all. They’re dead, every single one of them. And not just the men, but the women and the children, too. They’re like animals, and I slaughtered them like animals!”
Force-choking his pregnant wife.
For me, Anakin was a terrible Jedi.
