From all of the characters in the story, I feel the most for Lennie. Going along with the literary technique of naturalism, the fact that Lennie has a mental disability is because that is how he was born. There is nothing you can do that can change your heredity, and people judge Lennie on that all the time. George is the main culprit when he says that everything would be easier without having Lennie around. We all know that, but George doesn’t have to tell Lennie that to his face to make him feel worse about himself. Also, the other hereditary aspect that causes me to feel for Lennie is his size. It's not his size alone that makes me feel bad for him but it's the fact that Lennie doesn’t understand his size and how to control himself.
