[Marvel] It seems that they have some thing in common, but why do Frank Castle and Wolverine not like each other?

I think it boils down to that Castle kills jerks that could easily be arrested. 

He could, for example, subdue a serial killer and make a call to the FBI. The crook would go away for decades. But nope. Bullet to the head. 

Wolverine kills, yes, but only when provoked. Like when those soldiers busted in to the Xaiver mansion and started taking the kids. THAT gets you a stabbing. THAT Wolverine would gladly have worked with Frank on a cross-mansion murder spree over.
