Why do young people have to die?

Everyday you see or hear of an innocent, young person with a life threatening disease and/or death sentence. It seems so unfair! The bible tells us to live a good true life, but yet there are so many out there that do exactly that and die way too young. I have to say that it seems that I have known way more people who are haters and non-believers that continue to receive gifts from the lord. Then on the other hand there are young, innocent people who do not deserve a bad day; get their lives snatched from them way too young! Why does the lord work this way? It does not seem fair! So you can say that the troubled ones needed Gods hand; but what about the innocent children left behind by the good and honorable people that have been taken too soon? I know God works in mysterious ways, but I am fumbling to find the right path to what is supposed to be righteousness! Any thoughts??
