Is not that she follows only logic actions, it's more that she doesn't "lose herself" onto her emotions. If she was cold and logical she wouldn't care for the dude
But she does 'lose herself'. Tell me this is fear of death or punishment not and emotion?
I think feeling emotions and losing oneself to them is very different. she stated in the beginning that she would have gone crazy and offed herself had she not had the steel mentality effect. she still feels her emotions I just think once they get past a certain threshold the system cuts them down, but not off.
For someone who is supposed to make logical decisions devious of emotions, her actions are rarely logical and very emotional.
