Explain SMBC — the wiki for Saturday Morning Breakfast Cereal

This comic presents Superman standing at a podium, declaring "I stopped Superman from killing all of you once again." The joke is that Superman is framing his heroism not as protecting people from external threats, but as restraining himself from committing mass murder. The caption -- "Superman really isn't earning that key to the city these days" -- underscores the absurdity of this as an accomplishment worthy of civic recognition.

The humor plays on the idea that an all-powerful being's greatest service to humanity might simply be choosing not to destroy them. It's a dark twist on the superhero trope: rather than fighting villains, Superman's main contribution is just not being one. The comic satirizes how we celebrate powerful figures for restraint that should be a given, not an achievement.
