I think we have to make an important distinction between condemning the parent and acknowledging the truth that all people are imperfect. Imperfection does not equate with condemnation. If you are able to see your parent as imperfect, then it follows that he or she will sometimes make mistakes or even do wrong. You can then forgive while you keep in mind that this is not condemnation or disrespect. In fact, it is an attempt to see your parent as possessing inherent worth despite the imperfection. To me, this is a sign of respect for the parent as a worthwhile person.
