Pechorin, unlike most heroes, does not value morals. Moreover, he refuses to heed them in order to allow himself amusement. He tells himself that he enjoys hatred or other negative feelings from people because it is what he is used to. Whether or not this statement is true is debatable. I think that nonetheless he thirsts for emotion. If not in himself (for he is often indifferent/apathetic/bored) he seeks to bring it out in other people. Because of his interests in these things it is therefore impossible to appreciate values shared by most other men/women.
