Try having a deadbeat father who experimented on you like hers and you will end up like her. It's more like she has a pure hatred for bitch ass behaviour rather than total lack of empathy.Know how Chief Baek mentioned Karma's 3 abnormalities? I'm thinking we are seeing crumbs of one of them. The way she stepped in to stop Lee from hurting himself (him punching the mirror) tells me she still has that capacity for familial love deep down.
