Or HaChaim on Genesis 3:13/אור החיים על בראשית ג׳:י״ג

1 ויאמר השם אלוקים אל האשה. The Lord G'd said to the woman. The only reason G'd asked Eve what she had done was to give her an opportunity to confess her sin against G'd. The confession would act as the cure for her newly contracted sickness. When she said that the serpent had seduced her this was both a confession and an explanation that her sin had not been intentional. I have explained earlier that Eve had been under the impression that it was permitted to eat from the trunk of the tree. She had also not realised that the serpent was a seducer. She confessed her error to her Creator.
