Sometimes the medicine is harsh. We take for granted that Hashem is Rachaman but He is not a vatran and there is a middas Hadin and there comes a time to pay your dues. Think about it. Al pi midas Hadin the second any person does one aveira as small as it may be he should instantly drop dead because Hashem would stop allowing his heart to beat. But this never happens. Nobody likes to think about this but we all should have died the day we turned bar mitzvah and chayyiv in mitzvos. If you keep this in mind you have no questions about when Hashem allows the middas Hadin to do some cleansing. The absolute chutzpah us humans have to go against His will and smack Him in the face and then after doing it to Him a few thousand or million times and He sees that He must punish us instead of accepting the mussar we say how dare He!
