Casting Blame

When we as humans have problems, we like to cast blame. 

Why is this? 

Is it because it's easier to project our feelings and focus on a singular external object? 

Or is it because there really a singular source from which 90% of all human frustration and negativity exudes? Could it be that there is one object which--when eliminated--will create clarity and peace not only in our lives, but in the lives of other?

Fuck horses!
