I´ve been doing some research on "the bad guy" (in a relationship to a woman)
lately. And now, years after dealing with them in my teens,
and with more psych. knowledge, I look differently at them.....

I was wondering if actually this kind of behaviour
(sarcasm, not really showing themselves and their emotions to others, acting neglective or disrespectful on purpose, needing to be dominant in a relationship)
actually not roots in an overblown self-image but actually insecurity
about themselves and even aggression towards themselves...

I do not think that if one feels loving and not shameful about oneself, one feels the need to put others down, make oneself appear superior, never admit a flaw... this kind of behaviour.

This is what I found about sarcasm:

"
though they may not be aware of it, sarcasm is their means of indirectly expressing aggression toward others and insecurity about themselves." Sarcastic people protect themselves by only letting the world see a superficial part of who they are," says Steven Stosny, a Washington, D.C.-based therapist and anger specialist. "They're very into impression management."

What do you think? What goes in to making a guy a "bad guy"?
