I wonder how some people live with themselves

Knowing how evil they are. Do they take pride in it? Do they ignore it? Do they feel accomplished and successful? Do they treat it as their crossword of the day? Or do they have to make effort to put that part of their conscience to sleep? Do they think about it at night and feel the loathing for their existence that other people do?...... Or do they not think about it at all? Is it all just.... A reflex?
