That's interesting! I'm supposing you've been really afraid before, and you'll know it's quite an agitated state to be in. So normally, without fear, folks will be more at peace, more at ease.
As far as sociopaths and egomaniacs go, my experience is that they are usually quite fearful, though they try to mask it with compensating measures. You might feel bad for them if they weren't so often spoiling other peoples fun with their antics.
