3) Well, whatever you do, however terrible, however hurtful, it all makes sense, doesn’t it, in your head. You never meet anybody that thinks they’re a bad person. -- The Talented Mr. Ripley
Did you know that when psychologists interview serial killers, rapists, murderers, and con men, most of them believe that their victims deserved what happened to them? Even the ones that aren’t willing to go that far will usually excuse their own behavior and feel that they had no choice other than to do what they did. Now, if even hardened criminals tend to feel that way, what do you think the chances are that the guy who was rude to you or lied to you feels like he’s a rotten person for doing it? Not very high. Even if they have a conscience and believe what they did was morally wrong, they’re probably not going to judge themselves all that harshly. It’s biological. It’s how Nature built us. So, even if you’re dealing with other Hitlers and Stalins, just remember that they probably think they’re good people.
