1) Deadpool is (mostly) unkillable. His healing factor can be a determinant factor for his victory, just imagine: Deadpool can perfectly do an attack á la "suicide bomber" and he won't die, but I won't be able to tell the same from Slade.

2) You're understimating him, if green presidents ask him to kill someone, he just does it. He's not a good guy, he tried, but no. If he's willing to kill, he'll do everything until the guy we wants dead is dead.

3) What makes Deadpool even more deadly is his insanity, you won't be able what to expect from him.
