This is not a very good question. Consciously, things can happen without a reason and i accept that as true. Arbitrary accidents could kill people and there is no way you can find a reason to explain why someone’s daughter is dead in a snap of fingers. Life is arbitrary.
But unconsciously, we humans are always looking for connections and meanings. I guess that helps us to survive in horrible times. It’s just how our brains work and i accept that as well. I will look for connections and meanings in everything, or better, we provide reasons and meanings for the things that happened. It’s not right or wrong. It’s just how our mind works.
