why didnt michael kill...
..the baby?
shareHe didn't kill the black kid either.
shareProbably just left it there to see if anyone came to find it in time.
shareMichael doesn't see the thrill in killing something that can't hope to defend itself, and that express shock and surprise in the same way an adult would. Because it gives a perfect line in the sand. The baby is saved by it's very baby-ness, but not in an "Aww it's too cute/innocent way."
