Bias of finding others guilty of own shortcomings
Your first paragraph, in particular, reminds me of the 'fundamental attribution error':


  ... the fundamental attribution error (FAE), also known as the
  correspondence bias or attribution effect, is the claim that in
  contrast to interpretations of their own behavior, people place undue
  emphasis on internal characteristics of the agent (character or
  intention), rather than external factors, in explaining other people's
  behavior.
