Explain mary shelleys use of a motif in frankenstein and give two examples?

Abortion. Firstly through the abandonment and fleeing of his Creation and secondly when Dr. Frankenstein rips apart the Creature's "Eve" and hurls the pieces into the unforgiving ocean. As for the first one the Creature even says, "I, the miserable and the abandoned, am an abortion, to be spurned at, and kicked, and trampled on.” (Chapter 24 or the Walton section.) Good luck!
