No. No, you don’t.
It doesn’t have to. This doesn’t even need to be another thread about the death penalty.
Instead, maybe we can make it a thread about this.
Some things are real. Evil is one of those things. Really, not just as artifact of our culture, but really.
Some things, we as a society have called “evil” when they really weren’t. We have suffered for our cultural blindness in the past; no doubt we will do so again in the future. And the realization that sometimes we simply call “evil” whatever we don’t understand, and the reaction against that can be a good thing. Same-sex marriage, or equal treatment for women, or racial equality, or whatever - you can come up with your own examples.
But not this. This evil is not subject to cultural limitations. It’s just there.
Karl Barth speaks of God as the “Wholly Other”. I am not sure about that: if we came from His hands it stands to reason that we would have more in common with God than if we did not. I think of evil as the Wholly Other - something that we were not meant for at all; something that we want to remove ourselves from, or remove from ourselves. Maybe that’s why I want to kill and you want to lock him away forever.
Put away this evil from amongst you. One way or other.
