Most evil: Dio. Seriously, he killed and antagonized people for no reason every damn time. It's like he did evil things not for the sake of a goal, but just for the sake of being evil. There was literally no reason for him to fuse men with zombie animals, forced that one mayor to drive and then killed him, and tried to boss people around for no reason. Thankfully his interactions with Pucci and the implication that he actually loved his late mother gave him more depth. But I suppose Araki did intend to make Dio as menacing and infuriating as possible, in which case he succeeded. Kira was also evil, though he was too mentally unsound to realize that. He literally killed people to satisfy his kinks and then when they tried to stop him from killing more people he acted as if he's the one being threatened. He's one of my favorite villains though, he was very 'normal' but also very unsettling. It's scary because he didn't even realize that he's evil and thought of himself as a pacifist.

Least evil: probably Kars. I know most people would disagree, but despite being the most inhuman biologically, he is one of the most 'humane' main villain. He created the Stone Mask not just for himself, but for his whole species. So he's not just an egoist like most main villains at least. And a detail that most people forget is that his species actually tried to kill him first, he only retaliated. So it wasn't really his initiative to massacre them. He's also quite indifferent towards humans or Hamon users, he actually didn't mind letting Joseph and Caesar live shortly after he awakened despite knowing they're Hamon users. His whole betrayal to Joseph and Lisa Lisa wasn't just him being evil and sadistic, it was actually personal. If you reread/rewatch the fight between Kars, Joseph, and Stroheim in Swiss, you'll find out that he only started noticing and hating Joseph after he killed Esidisi. In fact, after growing wings he said that he intended to kill Joseph to avenge Esidisi and Wamuu as well as celebrating his rebirth. So, yeah, he's a horrible person, but torturing Lisa Lisa and Joseph was just his idea of revenge.
