Why do you think only human beings can be ethical?
I think only human beings can be ethical is because only humans are able to act
morally that we had intellect and will. So we are special and unique unlike animals that
are incapable of thinking just not the same of humans are capable of thinking the right
and wrong. And human beings have something that no other animal has, an ability to
participate in collective knowledge of humanity, in a way no animal can, our individual
abilities go way beyond what evolution has endowed us with.
