Interesting conundrum you present here; in lambasting someone for their actions we often inadvertently reveal an air of superiority whilst licking our wounds. Self-preservation really. I liked the way this was written, it was easy to imagine what terrible things the subject may have done, but I found it more intriguing to think about what the speaker of these words had gone through emotionally to inspire the contempt.
The flow and rhyming worked quite well too, nicely done :)

I have to agree with Anthony's comment on this one. I have read it several times and each time from a different perspective of the writer. Nice to have choices when reading. Well done.
