I enjoyed the philosophical questions asked by this poem. The struggle between good and evil, and right and wrong, is something that I think everyone can identify with. Similarly, I think we all ask ourselves at one time or another what our true nature is given our own inherent contractions and moral conflicts, and I think your poem did a great job of capturing the essence of those questions.

The two middle stanzas felt a little disjointed, which I think might be due to the imperfect rhyming couplets that don't quite match what you did in the first and last. While there's nothing inherently wrong with imperfect rhymes in poetry as a whole, having them side by side with other actual rhyming couplets accentuates the differences and makes for a somewhat uneven read.

Overall, I enjoyed this poem. I thought the subject matter was great and it was really thought provoking. There's a bit of room for improvement in the execution itself, but you've got a great foundation here to work with. Nice job!
