This poem says a whole lot more than the surface detail might seem to indicate.
It appears, to me, in two parts: the 1st, the imagery representing the subject's soul; the 2nd, the reason why.
I really like the way it is structured because of that - it begins by depicting a vampiric, callous creature that can nurture little sympathy from either its victims or the reader... Then it shows us that this creature -though horrible- is not beyond sympathy, nor even humanity. She, herself, is a victim - the effect of causes that are irreparable wounds inflicted upon her by others. The mosaic and caustic soul she now bears is the creation of the world itself.
A really good perspective, and revealing. She is a character that does exist, and this poem serves as her testimony, if not her defence. An interesting character study. Very good.
The first stanza was like dominatrix' confession, there is lots of sadism around, it has to be there, like the submissive one, and everybody finds what he needs; interesting that energy amount one would offer just for revenge, and so you believe in angels.... of course, they will help you. Archangels (heads of all hosts), and just plain old Angels, including our closest friends, the ever-watchful Guardian Angels. What impresses me about Catholic mythology is partly its tasteless kitsch but mostly the airy nonchalance with which these people make up the details as they go along. It is just shamelessly invented. well done; men love women in rage.
