We, humans, are not taught to consciously think about why we act or behave the way we do. The issue is control. People lose their sense of self authority, use of power and the ability to make decisions by believing and relating to outside authorities. It may be verbal or physical, harmful or not. Blame may arise from misguided emotions related to dishonesty with the self.
Humans are totally unaware of what real honesty is.
It can make you feel bad. Self worth and self esteem go down the toilet. No matter what happens, self integrity must remain intact in order to maintain inner peace. Developing self observation helps you to learn from your mistakes. So the answer is - not reacting to the blame projected.
