Anyone will murder a person if and only if subjective $ value of that person to me – political costs of murdering – murdering costs – “drops (such as wallet)” < 0. Babies have low sunk investment costs even from parents (at least till they enter college). Also murdering them is legal. It doesn’t have drops but I’ve heard their organ can be sold at black market. So they got killed. The same goes for cows, chickens, cats, mosquito. You don’t murder your friends and families because they’re useful for your own reproductive success.
So when someone is “murderous”, which variable differ? By the way I don’t have moral value. I just try to understand things. Trying to predict humans behavior the way they really behave, instead of the way they claim why they behave.
