Why do I have to be limited to one or the other? Why can't her guilt be a moment of weakness caused by the memory wipe? What if, as a result of that guilt, she "turns over a new leaf" as it were, in one playthrough, and vehemently rejects that in another, at some point down the line? Why do people feel this need to limit themselves to either/or when it could just as easily be all of the above?
