While, yes I agree that no one is without some fault-- there are degrees, the way I see it. I'm not sure what you are referring to but here's my stand on things.....

Sure we have all hurt someone in our lives-- but knowingly hurting a child or an animal is something I don't feel empathy or sympathy towards an abuser. Hurting adults is one thing but being an adult and hurting a child or animal--is a whole different story.(IMO)

And as far as forgiveness-- in such a case, I can only hope that the abuser will have to answer to a higher power when the time comes. I am not able to forgive such loathsome behavior.

Yes, like you say, behaviors are passed down in various ways-- but the bad behaviors, once we are adults, need to be stopped and or corrected in order to maintain a healthy life for oneself and for others around them.-- I like to think of it as "advancing" and stopping what could be/or was a cycle.
