When youre an insane mercenary with a healing factor and penchant for breaking the fourth wall, arrogance is probably going to be one of your strongest personality traits. What makes Deadpool such a hilarious and off-the-wall character is that he doesnt think, he just does whatever he wants. Why wouldnt he? He heals from almost anything, so charging into dangerous situations doesnt require any thinking or planning. The flip side of that is that anyone around him is inevitably screwed. To be fair, Deadpool doesnt purposefully go around killing innocents, but his antics often involve others getting injured in the process. In his world, hes the only one that matters, so why would he care about protecting others if it doesnt benefit him? Hmm, maybe putting him on a superhero list wasnt the best idea. Of course, when you get Deadpool hijinks, youre guaranteed a lot of wise-ass dialogue. Whether its teaming up with a Marvel hero or taking on a bad guy, Deadpool is always going to provide color commentary and annoy whomever is around him. Thats how sure of himself he is. No matter how dangerous the situation is, the combination of a healing factor and insanity has made the world into his plaything. Wed ask him to come to his senses, but then he wouldnt be any fun to read. Its probably best to just keep your distance and watch from afar.
