Anakin
Anakin has always been a bit of a d*ck, he starts as a bratty little kid, then a sexually frustrated angry homicidal teen in episode 2 then in 3 he's alright for an hour then he kills a bunch of people he deemed unkillable in episode 1. The rest of the saga is pretty self explanatory he kills a bunch of people. He never was a nice guy besides from the last two minutes of his life.
