Scientific Explanation of why people cry when they are sad?

Can evil people cry honestly?

• Just seen the video of Anders Breivik crying in court while he watched a video recording of his crime and it got me asking the question, can evil people cry honestly and remorsefully? There's a big debate as to Mr Breivik's sanity and I'm convinced he must be insane by the very definition of what he done. I refuse to accept that sane and rational people are capable of doing what he done. After seeing this video of him crying it has convinced me even more that he is insane because I don't believe evil people can cry honestly and remorsefully. - When I saw him cry, I could tell he was genuinely upset. What do you think, Can evil people cry honestly and remorsefully?

• Answer:

  Same thought passed through my mind as I watched the clip ...But even if he is insane, he can still express feeling, but it depends on the severity of his condition It may have been a period of insanity, and now back to his senses it dawns on him what he has done Or sometimes it takes an example of someone else to make them realise But when he came into the court room, he did a right wing closed fist salute...so that doesn't make him seem like he is repenting, but then again that was before he was shown the video. In my opinion, it was a burst or a fit of strong emotions, and now he may be beginning to feel a little guilty But you can never tell, we'll just have to wait and see.
