This past week's parsha, Parshas Shemini, discussed the death of Aharon's two sons, Nadav and Avihu.
I am posting two links on the topic of "Why do good people die young?"
Especially in light of the terrible tragedy in Itamar - yes, we have so many questions and are seeking answers. They are long posts, but the time you spend reading them is time well spent.
Part 1 explains how Hashem is so much greater than us, so beyond our understanding that as much as we know, we cannot understand.
Part 2 discusses more in detail why good people die young and why to them, they do not view it as something bad but as something part of the bigger picture.
I hope you gain as much from these as I did when I read them.
