If someone has a different opinion than me, the easiest and simplest thing to do is subdue them with ether and break their knees and elbows. In their state of helplessness, they can be fed to the pigs who'll devour everything, including the bones. As the pigs feed on their flesh, the person will realize how wrong their opinions were and they'll have some time to pray that they don't have to go to hell for being so wrong.
