Characters who have Died in Disgrace

In this case, the characters (mostly villains) commits something dishonorable or had no dignity to face their downfall. Related circumstances include:

• Villains who try to kill the heroes after being offered mercy or spared to live, only to end up dying in the process. Gaston, King Stefan, Clayton, and Murad are good examples.
• Villains who are killed by their own allies who come to realize just how evil the villain really is (Jenner is a prime example after being literally stabbed in the back by his own henchman, Sullivan; Aerys II Targaryen was slain by Jaime Lannister after Aerys told Rossart to detonate the wildfire caches, and ordered Jaime to kill his father and bring Aerys his head; Dick Hardly when the clones kill him after realizing that he never loved them; Emperor Palpatine when Darth Vader throws him to the bottom of the reactor shaft while he tortures his son and Rey Skywalker destroys him by turning his own power against him, destroying Sidious and his Sith Eternal cultists.); and Dong Zhuo when Lu Bu kill him during his revolt. Or were killed/abandoned to die by their superiors when they found no use for them or wanting to take over. (Examples are Miraz being killed by Glozelle in attempt to continue the war against the Narnians & Zommari Leroux praising & begging for help from Sosuke Aizen after being defeated by Byakuya Kuchiki).
• Villains who die in an ill-conceived, foolish, and/or desperate attempt on the heroes' life, such as an "I'm taking you with me" type attack that backfires (Good examples include Gleeman Vox's failed attempt to kill Ratchet, the Great Intelligence's reversed attempt to destroy the Doctor, and Pete Anderson's failed attempt to kill Rick Grimes, even trying to blame him everything that happened to him).
• Villains who try to weasel their way out of their predicament by trying to talk the heroes into mercy, only for the hero to realize that they have no remorse for their actions and kill them anyway. (Sentinel Prime, Raynare, Steven Jacobs, Arkham, Dandy Mott, and ironically Koba are prime examples of such). Arrogant villains or Egotists who spend their last moments questioning how they could possibly be beaten. (Luciano Bradley and Menomaru are good examples of this).
• Villains pleading/begging for their death when they are being suffered/tortured. (Cato pleads for help when he was attacked by the Mutt Mutants so Katniss, couldn't bear the agonizing moans, ends his suffering by shooting her last arrow at him; Szayel Aporro Granz, trapped in the drug of Mayuri Kurotsuchi, begs for his death, the sword coming closer, slowly through his senses, pleading it to hurry up as it pierces his heart, killing him; Hiling Care Before her mobile suit exploded by Allelujah Haptism, She was able to cry out to Ribbons for help her).
