Buddhism talks about the causal cycle. When catastrophe comes, many creatures die at the same time. Why do different "causes" lead to the same "result"?

Simply put. Although they all suffered great disasters, they also suffered misfortune. This is a common industry, but there are other industries, that is, the results of personal karma are different. Some people died, others didn't. The place of death is also different, according to karma, the six divisions in the wheel of karma.
