No emotion provoked from watching people die.
I've recently been on YouTube, and accidently stumbled up videos of people committing suicide. I, myself, am not feeling suicidal, and I never have, it was just a natural curiosity to view the video, and I had never seen anyone die on camera. At first, I was a little apprehensive and nervous to watch the videos, given the subject matter, but, eventually, I forced myself to. I was slightly disturbed, and I put heavy emphasis on the word slightly, but overall, I displayed no emotion towards the videos, and they were quite graphic.
I'm a regular gamer, and I frequently play games where the object is to kill people; could possibly they have desensitized me?
