Villains who died with honor
"I will not die a monster"
-Doctor Octopus, Spider-Man 2
Not every villain who dies dies an ignominious death. Some villains get to have their last moments be better than what most of their lives were, and end their stories in an at least somewhat respectable manner. Note that this doesn't necessarily have to entail redemption, but it usually does. It's also nowhere near as common as it's counterpart "Died in Disgrace", as the difference in size between these lists should clearly show.
