Just today I was reading Compendium 3, and I was looking at Carl towards the end.
I realized he started out, young, innocent. Just like the world. Then the world becomes awful, and Carl starts to become bad with it. He got shot by Otis, getting a scar like the world. During the prison he becomes cold, with the Gov. and everything, then he becomes hardened after his Mom and Sister are shot. At Alexandria, the world looks better and so does Carl, but he still is a little distant, where he may never change, like how the world will never be the same. Then he gets his eye blown out, and the war with Negan happens, and next thing you know the worlds shit and Carl is slaughtering Saviors. Then, finally, after the time skip, he starts to become a kid. Always scarred by Douglas and Otis, he will never have his eye back, similar to how the world is starting to come back, but still bears its scars.
Weird, isn't it?
