Why the Torah was given to Man

When Hashem wanted to give the Torah to Moshe Rabeinu, the angles protested. Hashem told Moshe to hold onto his holy throne and give them a (Teshuva) answer. The angels asked why the Torah shold be given to men who are going to sin, when it can be given to angels who are perfect. Moshe answered that the Torah was written for men not angels, the mitzvot are for men to do. But another answer that Moshe gave was Teshuva. Yes man will sin, but he can do Teshuva
