I certainly go out of my way to preserve the life of an outdoor bug that has decided to tour my indoor abode if I can help it. I figure that scooping the little guy up and tossing him outside is no more effort than killing it and disposing of its body. I figure if I was a tiny little guy just running around looking for food and something a thousand times taller than me came along, I would rather him not squash me.
Other than that, I do eat meat and am well aware of the hypocrisy of doing so. But maybe animals should stop being delicious.
