In what way can Cathy be seen as an Eve figure in John Steinbeck's East of Eden?

That Cathy of John Steinbeck's East of
Eden is a temptress like Eve of Genesis is evident early on when Adam Trask
falls in love with her; much later in Chapter 25 when Adam learns that she is a
prostitute and goes to see her, she tries then to seduce him.  However, he refuses her
advancements. 

Critics perceive Cathy Ames as a debased
form of Eve as the first mother, and mother of mankind.  For, she attempts to abort her
babies while she is pregnant, and she bites the hand of the man who helps to deliver the
infants.  After the fraternal twins are born, Cathy abandons them and shoots Adam in the
shoulder as he attempts to prevent her from leaving.  Further, as a debased form of Eve,
Cathy sees no goodness in anyone, merely seeking to use their trusting natures to
achieve her devious desires.  She is symbolic of the evil that will always be present in
the world as Eve is symbolic of the original sin and the loss of
Paradise.
