Moral Relativism

I think I get what you guys are saying. Like, it's wrong to kick a guy in the face, but if there's a black widow spider on his nose, it would be okay to kick him in the face to kill the spider so the spider won't kill him. In that instance, kicking him in the face would be morally right unless we were living 1,000 years in the future when spiders become more intelligent than us. Then, it would be wrong.
