I would argue that literally here is a modifier to murdering, and in fact both are used here in an intentionally excessive (or emotional if you prefer) in order to underline a point. By all means disagree with the point, but sugar can actually be figuratively murdering people. As an aside, to suggest that someone is using words to bias a discussion pretty much misses the whole point of mounting an argument, does it not?
