1. You have to be the Sefas Emes could ask the following question: What was the zechus that Pharoah had that allowed him to merit having a daughter like Batya and gave him the privilege of raising young Moshe Rabeinu in his house? He answers that this merit stemmed from the bracha that Ya'akov Avinu gave Pharoah when he met him. (We see the bracha of a tzadik can effect even the life of a rasha in ways that the rasha may not appreciate or even be aware of.)
2. The Sefas Emes and many others are bothered by Moshe's challenge to Hashem, "V'hein lo ya'aminu li," that Bnei Yisrael will not believe in him. Time after time after each cheit in the Torah Moshe Rabeinu comes to the defense of Klal Yisrael -- why here is he so reluctant to give them the benefit of his trust, even after Hashem promises him that they will listen?
My wife suggested that once Moshe accepted his role of manhig, he never gave up on "his" Klal Yisrael. We were like Moshe's baby -- our problems were his problems. However, at this point, before Moshe accepted his mission, there was not yet that relationship. When Moshe jumped into the job, he gave it 100% forever after, but that jump had to first occur to create that bond.
