They know who they are and what they're capable of - cross them at your peril.

No real hard bastard needs to brag or bully; most are modest, thoughtful and quiet. They have nothing to prove, as opposed to wannabe tough guys, who may pump themselves full of steroids or devote themselves to the study of a martial art, but can they handle themselves during an aggressive confrontation?

It is the real hard bastard's absolute willingness to fight literally anyone, his ability to be uncompromisingly violent, his complete lack of fear, and unwillingness to admit defeat that makes him stand out in a crowd. A real hard bastard exudes an unmistakable air of confidence and authority.
