Comey is a narcissist. It manifests as a Messiah Complex. He thinks he’s on a mission from God Himself.
It makes him feel entitled to ignore things like rules and laws. Those things only apply to mere mortals.
No one will ever convince him that he has done anything improper. Whatever he does is in service of his Higher Calling.
All narcissists have the potential to do a lot of damage. Nothing special about this one.
Think about it. Comey is finished.
What will he now do with his life? Cower, fear, regret, shame, anger?
Paranoia might sink in. That would be fun.
