Did God really "regret" making man? (Catholic perspective)

On the cusp of the flood and God's covenant with Noah, "who found favor with the Lord," Genesis 6:6 [New American Bible] states __[T]he Lord regretted making human beings on the earth, and his heart was grieved.__ And in verse 7, God says, __"I regret that I made them".__ This seems to go against the idea that God doesn't make mistakes. Engaging in a mass slaughter doesn't necessarily seem, for lack of a better expression, out of character, e.g., the Amorites. And making a covenant with a single man, Noah, seems quite reasonable. __But why regret the creation of man (and animals)?__ God certainly knew of the wickedness of man. It just seems an odd sentiment at an odd time.. Edit: With the possibility that "regret" is not the correct translation, I went to the Hebrew which suggests *second thoughts* might be an alternative explanation, but not sorrow. [Chabad.org] *6.ווַיִּנָּ֣חֶם יְהֹוָ֔ה And the Lord regretted* (Further explained:) For example: (Num. 23:19): “Nor the son of man that He should change His mind (וְיִתְנֶחָם)”; (Deut. 32:36): “And concerning His servants He will change His mind (יִתְנֶחָם)”; (Exod. 32:14): “And the Lord changed His intent concerning the evil (וַיִּנָּחֶם)”; (I Sam. 15:11): “I regret (נִחַמְתִּי) that I made [Saul] king.” These are all an expression of having second thoughts
