in the comic book universe, deadpool was mostly considered neutral and sometimes even evil, but near the end of the series he was proved to be a good person. he tried really hard to fight his own psychotic mind behaviour and stop killing people. he got married with a person that cared for him and had a daughter. he made friends with an agent of s.h.i.e.l.d. and by himself destroyed a whole evil army that was trying to kill his family. in the end, on a vacation with his family and friends, deadpool hugged his daughter as a second earth came crashing down from the sky, presumably killing him and his family and friends, along with many lives on earth, joining up the story with secret wars.
