When Pharoah increases the harshness of his work demands on the nation of Israel, after Moshe appears as an emissary of G-d, to Pharoah, asking him to allow Israel to worship G-d and celebrate in the desert (outside of Egyptian control), Moshe later raises the question to G-d: Why have you harmed this nation, why have you sent me? (See end of Shmot/Exodus chapter 5).
The sages as quoted by Rashi, compare Moshe unfavorably to the Patriarchs, Avraham, Yitzchak, and Yaakov, where they didn't raise questions on G-d, even though events didn't always work out on the surface level as favorably as one might expect for someone following G-d's orders.
Does one of the readers wish to elaborate, if one is already able to hold a conversation with G-d, what is the problem of asking him to explain, some of the seemingly strange things that go on in the world?
