What's very interesting is just how close this is to how he's portrayed in both "Uncanny X-Force" and "Thunderbolts"; sure, he's insane, but he's shown that he's a good man who, truthfully, just wants to do the right thing.
Stinkoman87 just wants to add something: he's funny, but in a raunchy way, and uses guns. Deadpool is what would happen if someone made Spider-Man in the modern age.
He also strikes a good balance between "Ax-Crazy murdering sociopath" and "Guy who honestly wants to do the right thing but keeps getting the Heel Face Door Slam". Just bloody enough to be badass, just annoying enough to be hilarious, and just messed up enough to be sympathetic.
The point isn't that Deadpool's a Good Guy by a reasonable standard. The point is that he's trying. A lot of heroes have an arc in their origin where they put on the cape, learn that with great power comes responsibility, etc. Deadpool started out on the other side and even when he fails (And he does. A lot.) he keeps trying. If Siren was the original impetus, trying to be worthy of her, Deadpool has gone way beyond trying to Get the Girl. There's a *reason* he can still work with the Marvel heroes whereas the Punisher can't. He's trying.
Aw, Shucks, Guys, You really mean That?
Enjoydamoment just wants to say yes we do Deadpool sir. You're the most balanced when you're unbalanced.
Death clearly seems to return our beloved Merc's affections more than she does Thanos's. Well, think about it: Thanos wants to destroy the universe, meaning no life. Death only exists because there is life. It's symbiotic. Whereas Deadpool just runs around killing people, no large-scale stuff. Still giving more to Death without threatening her existence.
Deadpool's healing factor keeps his cancer in check by constantly regenerating cells killed by the cancer, to the point that if his cancer were cured, his healing factor would cause him to grow new cells until it killed him (look at those Skrulls that tried to duplicate his power). One little thing: THAT'S WHAT CANCER IS! Deadpool's body is essentially two warring cancers locked in a permanent stalemate with each other. No wonder he's insane...
