10 Worst Things Superman Has Done in Official DC Lore

Superman is widely regarded as the ultimate symbol of hope, but even the Man of Steel has crossed moral lines in official DC Comics stories. From alternate timelines to moments of extreme desperation, these actions reveal a darker side to the Last Son of Krypton. One infamous example is his decision to execute the Phantom Zone criminals in the non-canonical story 'Whatever Happened to the Man of Tomorrow?', a choice that haunts him despite its alternate reality status. In other tales, Superman has resorted to lethal force against villains like Doomsday and Darkseid, blurring the line between justice and vengeance. Perhaps most chilling is his role in the 'Injustice' universe, where a grieving Superman establishes a totalitarian regime after the Joker tricks him into killing Lois Lane. These stories matter because they challenge the core of Superman's character: can absolute power remain incorruptible? They also serve as cautionary tales about the consequences of unchecked authority. As DC continues to explore morally complex narratives, Superman's darkest moments remind fans that even the greatest hero is not immune to failure.
