Oh well, I think you exaggerate a bit.
Let's look at the things in another way. I am feeling so sorry because Michael Jackson died, I also like him. I have all of his music, I am a true fan, but the thing is... Michael Jackson was a human after all. Even in the song "Will You Be There" he say "...but I'm only a human". Everybody is dying. Death is the only thing in our lives that we know it will happen for sure. Everybody is born, live, and then die... it's a cycle. I know it was too soon, at the age of 50... he should live much more, but we can't do anything right now. Let's say he could live a lot more longer... the moment of death come in a time. If you want to tell your kid about Michael Jackson, do it in a good way. Tell him/her that he was a great genius in music, he died soon, but he was a great musician. Let your kid to listen to his music, let him/her read about him but don't make your kid to be the same as you. Michael Jackson died and everyone is feeling sorry about this, but after all... it's not the end of the world. Is hard without this legend in the world, but his music will live on forever. Just think like that and it will be a lot more good for you.
And one more thing, you have to know that also many celebrities and great musicians died soon. There are also great musicians which died sooner than Michael.
Hope I helped!
