Characters ranked by villainy
1. Schofield Kid - Excited to become a killer, values fame and fortune above the lives of others. Murders unarmed Quick Mike.
2. Bill Munny - Willing assassin. At first he is planning to kill people who deserve it so he can better care for his family. He continues on even after he finds out Delilah is not hurt nearly as bad as reported. Kills Little Bill out of revenge even though he was told Ned was unintentionally killed. Kills four or five innocent deputies out of self defense. Worst of all murders unarmed Skinny for the undignified manor he allowed Little Bill to display Ned's body.
3. English Bob - Willing assassin. His purported past history (Little Bill's version of the murder of Two Guns and his reputation for being a killer of "Chinamen") paints a dishonorable picture. His finger gunning the Chinese guys on the side of the road shows he doesn't value all human life. He seems motivated by fame (Beauchamp) and money.
4. Ned Logan - Willing assassin. Seems to be motivated by money and concern for his friend. Shoots at cowboy even after finding out the claims against them are greatly exaggerated. He realizes too late what they are doing is wrong and quits.
5. Strawberry Alice - Posts bounty for the murder of cowboys. One of which seems innocent and the other seems deserving of lesser punishment (IMO something much less than death and worse than a whipping - castration maybe).
6. Other working girls - Their contributions to the bounty caused the foreseeable murder of the cowboys.
7. Quick Mike - Vile drunken crime against Delilah is deserving of harsh punishment.
8. Little Bill Daggett - Guilty of denying justice to Delilah in favor of the more locally connected Skinny and of negligently causing the death of Ned. Seemed to be motivated by peace, power and fame (Beauchamp). I found his treatment of both English Bob and Bill Munny to be harsh but acceptable by the standards of their times (He correctly identified them as assassins and ran them out of town).
9. Skinny Dubois - Greedy. Seemed not to care about the women other than in how he could use them.
10. W.W. Beauchamp - Not villainous. Could maybe have foreseen how he was adding flame to the fire with his ability to make people famous (English Bob, Little Bill).
11. Davey Bunting - Not villainous. Somewhat tried to stop Quick Mike. Offered to give Delilah a pony out of guilt for Quick Mike's crime. Was not part of any criminal enterprise - just a working cowboy with a psychopathic coworker.
