Why do people die unexpectedly? Why do good people die? Please use materialist philosophy to explain, not Buddhist cause and effect.

Death is a destination, whether it is old age or accidental death, it is just a form of destination. Everything in this world is the energy provided by light, so it can be said that life is created by light. It can be explained that no matter what kind of people are called in human beings, they are only for the view that good and evil are on the right side. A murderer creates karma through his actions, and a good man creates karma through his good deeds. Therefore, good and evil can be equated, only for material or spiritual ideas and produce different behaviors. Bugs, bugs. These thoughts push the fragments to form a complex secular world. As for death, it's like a black widow spider eating its male spouse.
