[DC] What is the worst thing a superhero has done?
gpt
There was the time when a portion of the League mindwiped villains who had learned their identity. And then gave Dr Light a lobotomy so he wouldn't be as dangerous anymore. And then mindwiped Batman when he tried to stop it.

And then there was Aquaman (before the formation of the Justice League) making plans what to do when the surface attacks Atlantis. The plans involved sinking the eastern seaboard and sending assassins after Batman.

And then there is Batman making plans to take out each and every member of the League in order to take them out in an emergency. Without their knowledge. The plans got stolen and nearly destroyed the League.

And then there's Barry Allen fucking the timeline (though someone else may have had a hand in that).

And then there's Hal Jordan going crazy, murdering the Green Lantern Corps and fucking the timeline worse than Flash (though it wasn't exactly his fault).
