It is so easy at times for a lonely individual to begin fantasizing about what the people outside are saying about him and, in result, irrationally and fearfully, and sometimes angrily, fancy himself a villain.

I won't be stuck in traffic 'til I see how rugged my path isAnd right now I'm loving how fast my troubles are fastingNo they don't bother me oh realizing I'm psychopathicA wild beast, baby I'm gladly running afterYes a thing called peace outlasting any madnessThe devil fears me oh he's feelingLike a fragment of a fractionNo he won't come near me'Cause his hat trick's out of practice

I think a lot of psychopaths are just geniuses who drove so fast that they lost control.

One either cares what others think about him, or cares what others think he thinks about them. If you want to find someone who doesn't care in the slightest what anyone thinks, try a lunatic asylum.
