i once heard a similar question, why do children suffer – in small ways? why do they get sick, get bubu’s, ear infections… to teach them that life is not so simple, it’s not all about ice cream and loli pops…to prepare them for the real hardships.
i think the answer to your question is – tzadik vera lo
did you ever hear the moshel of a king who got a top top tailor to make him a very exquisite suit? the other tailors were jealous and spread rumors that the tailor stole the rest of the material, and that he said he need so much material so he can take the remainders, that it makes no sense that a small suit needs that much material. The king wasn’t sure, and he demanded the tailor be brought to him. the tailor begged… finally he realized he has no choice but to prove himself that it was all used for the suit and stitch by stitch he began taking apart the suit. They all saw clearly that it was all used, he made it with a double lining – doubled the material. That’s the moshel i heard once to explain what it means when the malachim asked Hashem when they were killing R’ Akiva “?? ???? ??? ?????” and Hashem answered that if they say anything else the world will have to go back to ???? ????? so that they can understand everything.
