If superheroes were graded on general kindness shown, Deadpool would probably be the first to get an F-. That's why it's so surprising that he plans a Christmas party for more or less the whole Marvel hero roster - and even more surprising that he gets immediately kicked out of it. Given that normally Deadpool is hardly at boy-scout levels of morality, it seems strange that nobody thanks him once for what is a genuinely selfless deed, and instead exiles him the minute he makes a joke.
Sure, said joke is a tasteless one about the death of the Hulk, but getting mad at Deadpool for a bad joke is sort of like getting mad at Batman for brooding, or Spider-Man for shooting webs - there's just not much point to it, especially when he's fully rented and decorated a function room so everyone can have a nice time.
While Deadpool spends the rest of the comic pummelling a Roman god - which is an infinitely better way to spend the holiday season - there's something quite sad about seeing his moments of kindness and generosity totally rejected in such spectacular fashion.
