I've always failed to understand how I am responsible for the intentions of some other person.  The woman in the hypothetical above had no possible way of knowing that her assailant wasn't going to kill her.  I can't understand how she wouldn't be justified in shooting him. 

Let's try another:  My best mate Danny and I have a falling out.  Danny says that the next time he sees me, he going to cut my throat.  He goes round to all of our mutual acquaintances and tells them, 'The next time I see Boru, I'm going to cut his throat.'  He visits Big Mick's House O' Knives and purchases 'The Boru Throat Cutter Mark IV' knife, with optional eye gouging attachment.  He later sees me come out of a shop, draws the knife and screams, 'I'M GONNA CUT YOUR THROAT!!'.  He charges me, but I manage beat him to death with a cricket bat (like you do).  When the cops arrive, they find a note in Danny's pocket that reads, 'My intent is to just frighten Boru, not cut his throat.'

Should I be charged with a crime because I didn't know Danny's intentions?

Boru

addendum:  Any woman who kills the man who 'only' intends to rape her has my full support, whether or not she knows of his intentions beforehand.
