Declaring certain topics off limits for humor makes them untouchable, and then the only people who are making jokes about sensitive subjects are the assholes who are just trying to shock and anger people for shock and anger’s sake. People often forget that humor isn’t just entertainment; we need humor as part of the coping process. Deadpool’s approach to trauma is by no means healthy, but sometimes we need that kind of escapism—the idea that a character can look at their tragic backstory in the face and laugh at it. People point to Deadpool’s meta nature and his fourth-wall-breaking ways as the main appeal, but the fact that Wade can confront his brokenness with humor is what makes him resonate on a more memorable level.
