The rations in episode 2 were a great choice. I spent a good chunk of time trying to think up a fair way to hand them out and wondering if I was choosing who was going to live or die. Back then, I didn't know that it didn't matter who got the food ... I liked thinking that every little choice could have a big or a small impact.
The arm was an interesting choice. I knew that keeping it meant Lee was accepting that he was going to die, but I thought he could still his use arm or that it would be beneficial to not lose a bunch of blood while trying to rescue Clem. When I realized the arm was basically useless, I felt like I hadn't understood that the choice was either to cut it off because Lee was in denial or keep it for no reason except to look cool in a later fight.
The meat locker was an important choice, but I had to make it quickly, so there wasn't a lot of time to weigh pros and cons. I made the call to try to revive Larry, but I understand why Kenny killed him. The decision made a big difference to the relationships with Lilly and Kenny, but I thought they placed too much emphasis on it. If anything, the situation showed that people needed to talk about what to do if people seemed unresponsive, so that if it happened again, everyone would be ready to act.
I could understand if Lilly never forgave Lee for helping kill Larry (even if people thought it was necessary), but I didn't understand why Kenny held such a grudge because Lee thought Larry could be saved. So they disagreed under pressure. It didn't need to big that big of a deal, especially since no one had talked about what to do in that type of situation.
