Introduction of Literary Critique

I am mainly interested in critiquing Frankenstein using a moral critical approach. Analyzing the humanity behind a piece has always been something that I would like to do. I may also use a Darwinian approach as well, scientifically looking at the biological processes that may influence character decision. The main question I am interested in answering is: How moral is it to create someone and then forsake them, and is there a human reason behind these actions?

Moral / philosophical critics believe that the larger purpose of literature is to teach morality and to probe philosophical issues.
Advantages: This approach is useful for such works as Alexander Pope’s “An Essay on Man,” which presents an obvious moral philosophy. It is also useful when considering the themes of works (for example, man’s inhumanity to man in Mark Twain’s Huckleberry Finn). Finally, it does not view literature merely as “art” isolated from all moral implications; it recognizes that literature can affect readers, whether subtly or directly, and that the message of a work--and not just the decorous vehicle for that message--is important.
Disadvantages: Detractors argue that such an approach can be too “judgmental.” Some believe literature should be
judged primarily (if not solely) on its artistic merits, not its moral or philosophical content.
Critical Questions:What enduring truth is revealed in the theme of this work?
How are the actions of the protagonist rewarded and the actions of the antagonist punished?  (http://teacherweb.com/KY/BallardHighSchool/LivesayAPELit/Literary-Criticism-Overview.pdf)

I did some research and found this interesting point of view form Mary Shelley's husband:

In his 1821 A Defence of Poetry, English poet Percy Shelley proposed the idea that
imagination is the well-spring of compassion: “A man, to be greatly good, must imagine
intensely and comprehensively; he must put himself in the place of another and of many
others; the pains and pleasures of his species must become his own. The great
instrument of moral good is the imagination” (1904, 34). Such a moral imagination is our
ability to try to understand another, to make a good faith effort to inhabit anotherʼs
viewpoint— even someone quite unlike us. This idea of putting ourselves empathetically
into othersʼ shoes, of trying to see others as they might see themselves, is at the heart of
many of the worldʼs great ethical formulations, such as the biblical Golden Rule.
Literature, Shelley believed, offers us a particularly rich chance to practice that moral
projection  (http://apewiki.pbworks.com/w/file/fetch/51798592/Moral%20Criticism%20for%20Students.pdf)
