why people die young

On the other hand, death is the most fair thing in the world. Whether you're a king, peasant, dog, or ant, death comes for everyone all the same.

True. But why must some people die before their time? Why must people be struck down in the prime of life

Sure, that's sad.

It's very sad, and it's not fair

I guess it's a case of expectations... when you don't expect life to be fair, then it's not as much of a shock when you hear about people dying young.

Of course losing someone close to you will hurt a lot either way.

Wow, so rude calling someone tra--

Oh that's his name.

Death is preferable to some of the harshest things someone could experience. To be killed in some areas or instances is considered a mercy.

But I just don't get why Deity in whatever form it takes must let these young people die like that

It's not that hard to understand. Can you prove or disprove that we are living in a simulation? Like a video game. In the video games we create, many people are violent, could be the most popular shooter or the spark of rampages that many RPG players do. Maybe we are in a video game, a simulation of a troubled existence that doesn't mimic the utopian existence outside of this simulation.
You seem young, or at least lacking the experiences of the world. Just some advice, wouldn't ask such questions, you may find a road of cruelty eventually understanding some of the harsh realities of this world. You are better not losing your heart and head to such troubles.

There is no deity... death is a part of the cycle of life. Without death there is no life...without life there is no death.

Not absolute, no
