When i see disasters, or shootings, war, deaths, or other horrible events (even 9/11) on TV or radio- why?

why don't I care. i watch it and agree it is horrible, but nothing affects me. In fact the only reason i tune to the news is to see if there is "Breaking News". When I watch "Breaking News" i always hope for it to get worse, even 9/11(and i am an american). Is it a Morbid Curiousity thing? I'm normal in all other aspects (relatively speaking). I realized this while taking a human service cl and we visited a site which abused children and kids taken away by child custody services are housed, i heard (from the psychologist) some of the child stories. After the visit we had to comment on our thoughts: other students said they were upset, but i said i went to McDonalds, then home and went about my business as if nothing had happened.
