The Executor

From 2010, this DC Comics one-shot introduces a new kind of vigilante in Gotham City, as writer Jon Evans and artist Andrea Mutti explore the concept of a "legal" executioner. The story follows a man who, after the brutal murder of his family, becomes a court-appointed executioner, blurring the lines between justice and vengeance. This single issue presents a dark, philosophical take on the death penalty within the superhero universe, offering a standalone, thought-provoking narrative.
