This is a pretty messy subject to attempt to rate "assault" vs. "rape" vs. "murder" in terms of degree of harm. Some individuals would rather die than be raped, or rather be raped than assaulted, etc. How would people even go about trying to establish which is "worse". You can establish which crimes result in more bodily harm, you may be able to find statistics that demonstrate degree of emotional harm, but it just seems like an approach to the topic that doesn't have much chance at being explored objectively. Maybe you could say murder is the worst violation, but that should include those assaults and rapes that later result in death either through suicide or from complications. Beyond that isn't this discussion impossible for reaching "objective" conclusions?
