Although your comment is great and makes sense, you need to look beyond the human mind here IMO. Of course rape is bad as the way we see it. But I'm speaking of living or sustaining life. If we lived in a world where a no species gave "sex" givingly, rape would be how a species would survive.
For measurement of the "hot or cold" of course it goes without saying. This is basics I speak of, don't over complicate it with overthinking. All things exist a on plane. _________________ Every plane has extremes. The extremes are on the same plane just at different ends of it. Much like how you measure heat and cold.
You're not missing the point IMO. Just making a different point. Morality is a human concept. Not a universal one, as much as we'd like to think so. I was speaking on something surviving based on survival alone. When something is trying to survive it may seem immoral with the method of it, but it reality the entity is trying to survive/exist at any cost. Who's to say something doesn't have the "right" to exist?
