The thing is that human perspective changes the context of the actions. Murder, rape and violence are constants in the animal world and nature is often arbitrarily cruel. The reason we see these things as worse when done by a human is because of a supposed "free will" that for the most part is a scientifically flawed concept.
None of this changes what should be done when these things happen, though. Protection of innocent life should be humanity's #1 prerogative, along with protection of the planet.
