(Exodus 13:17) 17 And it came about at the time of Pharʹaoh’s sending the people away that God did not lead them by the way of the land of the Phi·lisʹtines just because it was near, for
God said: “It might be the people will feel regret when they see war and will certainly return to Egypt.”
(Judges 2:18) 18 And when Jehovah did raise up judges for them, Jehovah proved to be with the judge, and he saved them out of the hand of their enemies all the days of the judge; for
Jehovah would feel regret over their groaning because of their oppressors and those who were shoving them around.
(Judges 21:15) 15 And
the people felt regret over Benjamin because Jehovah had made a rupture between the tribes of Israel.
(2 Samuel 24:16) When the angel stretched out his hand toward Jerusalem to destroy it,
Jehovah felt regret over the calamity, and he said to the angel bringing destruction among the people: “It is enough! Now let your hand drop.” Jehovah’s angel was close to the threshing floor of A·rauʹnah the Jebʹu·site.
(1 Chronicles 21:15) Moreover, the true God sent an angel to Jerusalem to destroy it; but as he was about to do so,
Jehovah saw it and felt regret over the calamity, and he said to the angel bringing destruction: “It is enough! Now let your hand drop.” Jehovah’s angel was standing close to the threshing floor of Orʹnan the Jebʹu·site.
(Ezekiel 24:14) 14 I myself, Jehovah, have spoken. It will come to pass.
I will act without holding back, without sorrow, without regret. They will judge you according to your ways and your dealings,’ declares the Sovereign Lord Jehovah.”
One word in ancient Hebrew had several different meanings, to convey different thoughts.
So, regret - also meaning grieved - is used in these verses, showing God's strong feelings of grief or pain, over something, and since God did not think there was anything wrong with his creation (Genesis 1:31), but loved them enough to make a way out of the mess Adam created for the human family - sending his beloved son (Genesis 3:15), who expressed that he was fond of mankind (Proverbs 8:31), then I understand the verse to be basically saying that God was deeply grieved at the way man was made / became / turned out... Not created.
The scriptures say,
God "made out of one man every nation of men to dwell on the entire surface of the earth. . ." (Acts 17:26)
So through Adam, God made mankind.
As I mentioned to
@Alien826, God took responsibility for allowing man to be in this state.
Since the creator wanted the best for his creation, it grieved him that they would suffer in the way that they would.
That, to me is admirable, for the reason that it demonstrates the magnitude of God's unfathomable love. His patience, and endurance, having to experience that for thousands of years (We only experience it for 10-80, or 90 years).
It highlights too, God's unswerving justice, in sticking to his standards of true righteousness - not abandoning his purpose... but then, for an all powerful being to abandon his stated purpose, and will, would only render him weak.
I see wisdom in what God has done.
I think though, this has to do with a number of factors. Humility, comes first, but then other qualities are added (Galatians 5:22). I believe this leads to understanding. (Matthew 13:10-16)
