The Cathars were abortionists and used birth control because they didn't want to bring more children into the world. They were described as having "unnatural sex practises." Innocent III wiped them out.
Innocent wiped them out because it was a rogue religion. Simple, Catholics didn't take the crap back then, simple as that, they wiped out paganism, cathars, etc.
