Só few mentions of Enel, he not only killed his own people, he was going to destroy the other Island just because it existed as he was about to leave anywyay.
Absolutely zero care about anyone, no f's about his subordinates or whatever
Even Garling at least seems to care about his son's, even if perhaps just a goal or a legacy.
Enel is probably incapable of empathy, it's just that he is really charismatic as villain to watch
