I'm honestly just so glad that Rick carved that guy open when he did. Cinematographically, I would have liked to have done it a little differently, but that's only a nitpick, and the real good thing about it is the storytelling, and they did that pretty much perfectly. They NEEDED Rick to make that kind of decision as soon as it became clear the guy was okay with getting Rick killed (pushing him into the zombie)

I was afraid it was just gonna be more talking and rationalizing and not doing anything. But instead they cut the guy open exactly how he should have been. Finally something of meaning in the story
