Ahh, but if we have a chewey, caramel center, then who's to say we'd want to eat it? Really, who here likes the taste of blood and viscera? The very idea of eating -that- kind of icks me out. So it logically follows that if we had a chewey, caramel center, the idea of eating caramel would be pretty much repulsive.
I guess what I'm trying to say is that we'd be candy people, hunting candy animals and eating candy veggies, and we'd still find cannibalism repugnant.
