So... i'm happy about someone being dead.
Wow, that's bold to admit. Why are you happy about that?
You must be a very nosy person.
You expressed your feelings about this person. I'm just trying to understand why you feel the way you do.
I'm worried about someone's life.
If you are worried about someone's life, but glad for someone's death it sounds like there is a larger issue at hand. Was the person who died abusive or bad? While it is disrespectful to feel happy about deaths, there can be exceptions.
