You are completely wrong in EVERYTHING, except for one thing. And that is the "they've entertained you on TV" part.
Quite frankly, I don't feel as if I lost a friend or any crap like that, I just feel as if a part that entertained me is no more. Gone. History. And that's not cool, heh.
People don't know that celebrity, which leads me to the whole point: All they know about him/her is the amount of entertainment that person offers the viewers day by day. That's what they really miss. That's what they don't like losing.
Most actors get themselves wrapped up in some really heavy ****. I mean I don't know about you, but I've never heard about an actor that died peacefully in a rocking chair or anything like that. If so, I bet it rarely happens. It's either drugs, alcohol, stress... so I'm not all THAT surprised about this heavy twist... although yeah, killing your own son and wife... that is just plain sick and makes my stomach turn.
Why does almost every single celebrity death have to be such a ****ing skandal though...? I keep asking myself that question...
