Again, there's a massive difference between not having sympathy for someone compared to actually taking joy in their death.
This is going to be my final statement in this thread. Many years ago when I was around 12 I was in a children's theater group. This was supposed to be a place where you could be yourself and hang out with similar kids without the pressures of school. There was a kid around my age that made my life hell. He bullied me mercilessly and I despised him for it. I don't know if it was because one director really liked me and the other director was his mom so we were always in similar roles, but the kid just really felt threatened by me. I had a massive crush on one of the girls in the company so I gutted it out. This went on for a few years until I quit.
One day my mom told me that he died in a car crash. I think he was 15. His brother in law was driving him back from the coast, tried to pass into oncoming traffic, lost control and went over the embankment. The brother in law didn't have a scratch but sadly the kid did not survive. This was 24 or 25 years ago and I still remember the range of emotions that I felt when I found out he died. Happiness was not one of them. This was a kid that I hated. He had an active role in making my life worse. I had every right to detest this person, but I wasn't happy that his life ended. It was a strange feeling that I'm not sure I can describe. One minute he existed in my world and the next he was gone. I wasn't sad that he died, but I wouldn't say I was unsympathetic. I struggled with hearing so many people gush over how great he was. How he was such a positive influence. I realize that we remember the best in people who die around us, and maybe there was a side to him that I never got to see, but I never saw it.
The aftermath of his death was massive. His sister and brother-in-law split up, which was especially tragic because they had a newborn. His mother and father split up. His mom pretty much went batshit crazy as a result of his passing. His close friends were all clearly changed as well. All of this to circle back to my point. While I can understand why someone might not be sad or even sympathetic that someone died, I personally cannot understand being happy or celebrating their death. That's a dark place that I personally will never go.
