Part of my difficulty is that some humans, such as infants, have less blicket than animals. If its ok to kill animals, then there's no reason to say it's not ok to kill blicket-less humans. Then I realize that even though it's legal to kill animals, it's still something I can't do for anything except certain bugs. Even spiders I let be, or take outside.

Don't worry, there would probably be a baby killing service if it were legal. Just like we have other people to kill animals for us.
