There are things about Noah that weren't all that good either. They look a lot worse if you consider probabilities of "reading between the lines" probes into the Biblical record. "But Noah found grace in the eyes of the LORD." (Gn 6:8)
God's promise that the seed of woman (an egg, an exclusively female form that was the initial manifestation of the incarnation) would crush the head of the serpent (snake, copper,divination,discernment, cast a spell) may have come close to being subverted by certain "sons of God" or, the "Rephaim," born of "sons of God" and human females. Whether it was Angelic beings not keeping to their assigned sphere of being (per Book of Jude) descending into the physical or possibly the biologically bisexual offspring of Adam before he was put into a deep trance state (from which we are not awakened until Christ shines on us) where God separated the curved chamber from his (bottom) side, constructing it into a female. It is possible that one of these were the ANUNNAKI (Sumerian meaning: "Those who from heaven to earth came," Biblical Anakim, Nephilim) that have been said by the Sumerians (the oldest culture, possibly including pre-flood, who preceded the Chaldeans from which Abraham was called out) to have visited earth in it's early history. There is much surprising information corroborating accurate knowledge (not gone into here) of the nature of relevant planets we call Neptune and specially Uranus, which Sumerians called MASH.SIG meaning it's color blue-green, different that of other planets and only re-discovered by Voyager 2 in 1989 fly-by. Interesting that the largest (inverted, step) pyramid in the solar system (as far as we know) is on Mash.sig, etc.
By making a hybrid between two species there would be no more "seed of woman" to fulfill God's word. The Great Deluge was the remedy.
