Chasidut do Rodzaju 6:5

And this is the explanation of the verse "And Hashem saw that the evil of the humans on earth was great" (Genesis 6:5), that is to say, at all times that one is on earth and one's evil is great, ["and all the humans' impulse of thought in their heart"] through that, also the one who wants to serve the Holy Blessed Name and does not do evil, even though one's thought reins that person in "only evil all day", "and Hashem nacham [had pity/regretted/consoled]" meaning, there was a consolation for the Blessed One in that a human could exert effort in front of the Blessed One, "that he made the humans", meaning, like the saying of our sages of blessed memory: "were it not for three verses etc " (Sukkah 52b and Berakhot 31a) and one of them is "that I made evil" (Micah 4:6) their hearts - that I gave them the impulse to evil. "And God was sad in his heart" - meaning, that the Holy Blessed name was sad due to the heart of the human, that God had given the human a heart of stone like that. "And Noach found favor" (Genesis 6:8) - meaning, that Noach was a tzadik and switched himself from the nature that makes humans likely to separate themselves from clinging to the Exalted Creator and strengthen oneself to cling to the Creator, and so [Noach] found favor, Noach with switching the letters becomes Chen, favor, which is him becoming favor in the Blessed Name's eyes.
