To a biologist, both love and hate are similar emotions. Both use a few similar regions in the brain to produce those emotions. The brain shuts off logic in both cases. While in love, it shuts off more regions in the brain because they are less judgmental with the other person. While in hate, depending on the level of hate, people need to use their brains to criticize and plan attacks. At similar levels of hate and love, your hater’s brain works more to think about you than people who love you
