I divorced Joss from the characters a long time ago, and I disregarded the comics almost as soon as I heard of them, so no, whatever Joss does in the comics will not make me dislike Spuffy at all.

But it may take my Joss dislike to as-yet-unheard-of heights.

In fact, I disregard the comics to the point where I don't believe Giles is dead.
