“My question is, how and why would a being who has no soul, and no conscience, and no ability to judge between morality and immorality, suddenly become capable of perceiving it [Spike's attempted rap of Buffy] as a "wrong" which needs to be "righted"?”
“Entertaining for a moment that it is purepsychology, the that "soul" is a concept in the imagination and nothing more, what can we determine? Also, for a moment, completely rejecting the treatment and use of the soul concept in the Buffy series because of its contradictory presentation and because of its negative potential, the question then becomes, if there is no such thing as a soul, then what about redemption? Is it possible in the Buffy worldview...for any being to be redeemed without a soul?”
“One wonders if Spike would ever have achieved true decency or validity in their [Scooby Gang] eyes, no matter what he did, as long as he was missing the thing which they believed makes a being valid, worthy, moral, and redeemable- a soul.”
“...the presence of this thing called a soul, and only this thing called a soul, makes a being in the Buffyverse capable of choosing to behave in a profoundly moral way or makes a being capable of redemption.”
“He [Spike] has already demonstrated a capacity to love, already demonstrated a capacity to be selfless, and, possibly most importantly, has demonstrated that he has a conscience.”
“...use of the soul in Buffy: a personal or cultural belief which is blind to all else, which refuses to acknowledge gray area and insists on its own infallibility, as we've seen in our own history, is dangerous and detrimental.”
“Redemption becomes possible when we strive to find selflessness, conscience, and a capacity to love within ourselves where before there was none.”
