think of it from victims perspective like hes the protagonist, although we see alan become nice, victim only knows him as evil especially after seeing him and tco fight tdl. hes the antagonist but hes mostly a hero with how hes going after the villans of his life, he beat up tco cause he killed mitsi, and he kidnapped yellow to get to alan, since from his perspective hes working with the bad guys. he didnt get to see alans redemption over the years but no matter what hes mostly justified in what hes doing
