As a follow-up on my previous HuffPost blog, I further expressed some thoughts on how someone doing evil can develop the perception that he/she is not, even doing good. See this in my latest Huffington Post blog: Do Evil People Know That They're Evil?
original title for the post, btw, was 'Evil as the Delusion of Good' but it
was changed by the editors. (I leave it to you to decide which title is better.)
feel free to comment here or there.
