I'm not so bothered by the age difference personally, is just that a lot of the stuff that he pulled in the 90s should make the X-Men hate him regardless of their circumstances at the time of his second heal-face-turn. Deadpool... look i like the guy and he is more complex that people give him credir for, but the X-Men or Avengers should never work with that guy considering (again) the stuff that he pulled in the 90s too, people should be nicer to the Punisher than they are to these 2 dudes.
