Story spoilers
Hartmann is trying to shape him into another leader like Johan. After Tenma rescues him, Dieter becomes more optimistic and follows the doctor in the search for Johan, partly because he wants to keep Tenma from becoming a murderer. He later supports Nina when her traumatic memories resurface, drawing on his own experience of abuse.
