Remember Reiner's split personality? Ymir talks about it when they are in the giant trees after kidnapping Eren. She theorizes that apparently Reiner, as a result of the demands and stresses of going deep undercover at a young age for so many years, had apparently taken on the identity of a 'soldier', someone who is actually part of the world within the walls and accepts the motivations that such a person would have, and a 'warrior' who is a homelander. Reiner the warrior killed Marco with such conviction but Reiner the soldier was shortly thereafter shocked that Marco was getting killed.
