You recite Genesis 6:7 as if God provides a rationale for the Flood. None is actually provided.

Likewise, you insert details into the matter of Eve and culpability. Eve is said repeatedly in the Bible to have been "deceived" (2 Cor 11:3, etc.). She's the victim of the lying serpent. She is not punished. There is no curse on her.

She was lied to and then she had to wise up. Similarly, if someone believes you, they're not "bad," but only deceived.
