I thought that the first time I read it and still do.  There are many
ambiguities in "Spinner's End" that lead one to doubt whether Snape
really knows about the plan. This from Narcissa is particularly
suggestive that Harry is the object of the plot.

"But he won't succeed!" sobbed Narcissa.  "How can he, when the Dark
Lord himself--?" (P. 33, AE)

Another fill-in-the-blank.  "...when the Dark Lord himself has tried
and failed"? Voldemort has tried and failed to kill Harry four times.
Or "...when the Dark Lord himself is afraid to try"?  The Only One He
Ever Feared.

I don't believe Snape agreed to the vow because he was willing to kill
Harry.  I don't think he planned to kill anybody.  I believe he was so
complacent about his own cleverness, he simply took one risk too many.
  I agree with the theory put forth by others that the UV was the
first manifestation of the DADA curse and that the curse worked
through the character flaw its victims. Snape's was intellectual
hubris.
