I found this timely from a blog I follow:
There are people who insist on holding on to resentment, often inventing situations in their minds that never happened, justifying their bad behavior, and putting the blame on others. They see themselves as the abused party, always quick to take offense. Rarely are they able to have healthy relationships, for they are in reality, the abusers. Their world centers around them, and any attempt by others to appease them, only contributes to the anti-social behavior.
Such behavior betrays a deep spiritual and psychological illness, one that is not easily healed. Such people feel empowered by making other people uncomfortable, and normal attempts at rapprochement often end in failure, for such people are always looking for ways to continue their control over others. Their illness is difficult to heal, for their pride and deep seated sense of superiority makes repentance difficult, for they simply don’t see themselves as having a problem.
