10 Worst Things The Green Lanterns Have Ever Done

10. Hiring The Guy Who Killed Mogo - Green Lantern Corps (Vol. 2) #60

In terms of Green Lanterns who have had it rough, John Stewart is perhaps the most overlooked of all. He's initially almost rejected out of the Lanterns because of Hal Jordan taking a dislike to him, and continues this train of misfortune through most of his superhero career - right up until he kills Mogo, in the worst move of his entire career.

For anyone not versed in who Mogo is, he's kind of a huge deal for the Green Lanterns, because he's a living planet who's responsible for sending Green Lantern rings to their new owners whenever one frees up, meaning that without him, the whole process becomes infinitely more tricky. Worse yet, John doesn't kill Mogo because he turns traitor - no, he kills him because he's been mind-controlled by a villain named Krona, meaning that he actually killed a totally innocent being.

But this can't be blamed on the Lanterns themselves, right? Wrong! Because immediately after murdering Mogo in cold blood, John is reinstated as a Green Lantern, in a move that feels undeniably sketchy as hell. Sure, he did what he felt he had to - but they also just immediately forgive his cold-blooded murder seemingly without even a chat about what happened, which is super messed up.
