It’s not that empathy itself automatically leads to kindness. Rather, empathy has to connect to kindness that already exists. Empathy makes good people better, then, because kind people don’t like suffering, and empathy makes this suffering salient. If you made a sadist more empathic, it would just lead to a happier sadist, and if I were indifferent to the baby’s suffering, her crying would be nothing more than an annoyance.
