Is it wrong for me to laugh at something I see every day (death)?

In my previous question about the Twin Towers, I told the TRUTH about laughing when I saw the buildings exploding. It wasn't because of the current president at the time. It wasn't because I'm an evil person (which I'm not). It's because at that time, what I seen was REAL. People who was on ground level was really zooming to get away from there. Which I thought was funny. The lives lost that day was not. Just the scene. When Saddam was hung, people laughed, applauded, I mean, they were happy to see him die. So when people get mad at me for laughing at something I thought was funny at the time being, I find it very hypocritical for people to be mad at me when, not just Americans, but almost everybody honors death. My questions are for the people, you people, to answer with your hearts no matter what the question is. When I die I want people to be happy not MAD. I want them to smile (even when crying). And if I get murdered, I don't want anyone to WANT the person who murdered me to die even a worser death than I did. JUST WANTED YOU PEOPLE TO KNOW. THX FOR LISTENING AND ANSWERING.
