My first impression of this is I like it but there's room for improvement. There again, when isn't there?
Again, a very simple poem and you should probably add more imagery and extend it because at the moment, it makes the reader think but it's very impersonal. Try to bring the emotions out more so that the reader can feel the hurt and betrayal that the persona does and don't use too many rhetorical questions. One or two can be effective but if every sentence is a question, it loses that effect and the reader loses interest.
Overall, I like the idea and you have a nice structure. With a little work this could be even better though.
“Can a magician kill a man by magic?” Lord Wellington asked Strange.
Strange frowned. He seemed to dislike the question. “I suppose a magician might,” he admitted, “but a gentleman never could.” — Susanna Clarke, Jonathan Strange & Mr Norrell
