I maintain that socialization is king here. Morality is a communal construct. Isolated animals (humans included) invariably fail to learn to adapt to social codes, including morality. If morality was essential, we would expect to see moral behaviours in developmentally isolated humans and animals. We don't. So we create morality. Why? To help us get along for the exact reasons we learn to speak and assemble in groups.
See now this is a weird statement from you, I think. "Freedom"? What's that? In a "free" western society fundamentalists are vilified. In a fundamentalist society "free" westerners are vilified. Both "freedom" ideals are based on moral ideals, and freedom is no less aesthetic than morality. Saying some societies are "free" is a value judgment based on...For some the variable is much more fluid, and in societies where freedoms are more restricted, it's obviously less so, and it's less a function of the individual's whim, psychology etc.
Most of the time, I murder spiders. Sometimes, I euthanize them after my attempt at murder fails. (why is there no satan smiley???) I'd suck as a buddhist.Killing vs murder? Aesthetics and semantics. Killing is an action, murder is an aesthetic evaluation.
