So you can look at said lyrics here and follow along with me! This song is from the perspective of John Proctor who is the aforementioned adulterer. He is saying that she who in the play becomes revered as a saint is the only real witch, especially considering the fact that she drank blood as a charm to kill John Proctor's wife. And he is now being seen as a heretic because he hates Salem's pastor and therefore he doesn't go to church very often and when he is being accused of working with the devil he says (because of the corruption occurring in Salem) that "God is dead!". So in the first verse he wonders how Abigail could be so cruel as to sentence thirty-something people including him to death. Then he talks about how she is a "product of lust". I am of the mind that if John had never had his affair with Abigail, none of the deaths in the play would have occurred so that's what I think he is saying by her being a "product of lust"- everything she is doing is, as is said in the play, "A whore's vengence". Then he goes to mention the fact that John Proctor is eventually hung as the people of Salem watch and even cheer. And John had been a pretty upstanding citizen and hoped perhaps that the people would see the corruption happening when he was actually hung.
