I can't remember the exact name, but there's a common process with ongoing characters where the writers find themselves making their toughest characters nicer over time.

Both Wolverine and Jack Reacher were presented as unapproachable loners at first, and both mellowed considerably over time.

Rorschach was 'lucky' because he got to die a noble death before being forced to become civilized.

He's also capable of backing his words up with actions. Although in the prison scene I guess the actions came first.

Pretty sure the "you're locked in here with me" vibe. is what all the fanboys envision themselves as, but would never actually be to emulate.
