Why Angel of Death?

I found the reading quite straightforward as well as interesting. The example of Snow White resembles a lot to Freudian interretation of the story of Oedipus, but I think it is meant to be similar. I think the author draws the conlusion (if I nderstod it well) that there are two kinds of women representation in patriarchal writing: the active, loud (writing/speaking) monster, who has authority, therefore she i masculine and the passive, silent angel, who does not have authority, thus she is feminine. I only did not get the part about the how women become th "Angel of Death". and how or why they "kill themselves into art in order to appeal man". I do not see how the image of death comming into picture, though I have read page 14 through more times, which I think sort of explains it, but it did not explain it to me clearly enough.
