More like Brian Blackwell. It has to be a form of rage rather than just anger as rage operates at a more unconscious, primitive and deeper level. Blackwell was in many ways a talented and productive member of society but he still flipped and killed his parents in the most appalling way. Blackwell was diagnosed with NPD. People have more conscious control over anger than rage. Many with NPD have a fake persona with unnatural levels of superficial charm which they use most of the time.
