Why Blame Others?

What is the psychology of blaming others or society? My thoughts:

The psychology of blaming others

The basic gist:

I suffer. Why do I suffer? I don’t want to believe that I’m the cause of my own suffering. I must scape-goat my suffering onto someone else — whether society, the state, government, or any form of “ism”.

Perhaps blame is some sort of deranged psychological condition in which an individual has no faith in his or her own personal strength, and must allay their blame and suffering upon another entity. The scape goat notion might be a distinctly human one — note human sacrifices and such. Rene Girard (Peter Thiel’s mentor) seems to has espoused this view.
