If we allow ourselves to identify too closely with literary figures, then we also take away our own ability to grow. That does not mean all such characters should be devoid of humanity; the opposite is true. We need to see all ends of the spectrum. There needs to be that character who struggles with his own internal conflict. But by the same nature, we also need to see that despicable being who remains despicable. It shows us how to resolve the conflict a little more. After all, we have a choice with our own heart in conflict; grow and become a better version of ourselves, or continue spiraling into a self-absorbed monster whose only goal is his own satisfaction.
