Sadly this totally defines my SIL/godson! Doubt therapy can fix this, but perhaps God can. My advice though to those around these people - self preservation dictates, get away as fast as you can and stay away, far, far away!
Psychopaths generate pity plays for many reasons. But it is especially dangerous because they use the poor me routine to manipulate their targets into forgiving them and giving them chance after chance after chance, thus perpetuating the cycle of abuse.
