>But then again, killing another person is just how nature works too, right? I eat meat and will eat meat forever, though I can't help but feel like such an hypocrite for doing so while condemning murdering people.

I fail to see the hypocrisy. You condemn murdering people because a) they are your OWN kind, and b) they have brains capable of writing HN posts.

How about just constraining our moral obligation to just: don't eat/murder your own kind?

Let's get to that first, abolishing capital penalty, war, murder and such, and then we can worry about eating steaks and/or prawns...
