Have you come across people who blame others for their troubles?

I have an example to explain. There was a king who was never defeated before.One day he was defeated in a war.
In the gloom of defeat,he became indiscreet & blamed 4 horses & the rider of his chariot & he killed all of them.He thought they are the main culprit for his loss in the war. The king won many wars in the past with their help, nevertheless he killed them all.

I always see the people who appreciate in someone’s presence but blame,satire in absence of someone.

Have you seen such indiscreet,blameful people in your life?
