It looks like they caught another very bad guy. What really gets me is that almost everyone who knew him were shocked that it was him. Well, not everyone. The theory apparently is that his daughter knew something and gave dna.
My question is what kind of circumstances make a guy do this stuff. He seemed to have a certain affinity for the spotlight.....but aren't there a myraid of ways to find it besides killing people and writing letters to the media. This marks a person profoundly devoid of empathy. Maybe a little sermon that all the pastors, priests, rabbis, mullahs might want to consider. The meaning of empathy. Not sympathy like understanding how you feel but empathy , being able to put yourself in someones position and understand it from their perspective. This man could not have been able to do this if he was at all skilled at empathy. What else is going on here? Please discuss.
