Zinnia, not trying discount how you feel but your argument for the possibility of snakes having emotions comes crumbling down when you realize that there is a physiological basis for emotion. Emotions are not just some thing that is floating around out there and takes place in humans and other primates (and maybe even other mammals). Emotions are produced in areas of the brain, and reptiles quite simply LACK these areas of the brain where higher-order reasoning take place.

From a biological standpoint, its quite simply impossible for snakes to experience emotion in the way that you describe. I encourage you to research the topic and you'll find that the reptilian brain is one that simply responds to stimuli and functions on instinct. Emotions are just not possible with the set of equipment that nature has provided them.
