I sense these are of 2 type:
1. Those who lose their conscience so they just dont have the inner voice which tells them what is right and wrong so they are arrogant and the world is plain and simple for them. They are also not open to advise or correction. They say" I didnt do it".
2. Those who are absolutely stupid, they make mistakes and they cant see it. When they do good, they do it by mistake, when they do bad they cant see it too. These people are like emperors in their own dreams. They think "it was never my intention".

Funny indeed. Nice topic.
