Most people wouldn’t knowingly poison babies they know, or babies of people they know. The root of cause of disregard for a group of people is anonymity, which in turn is a consequence of large and dense groups of humans. Unknown "others" just aren't real. We feel attracted to huge and dense cities/provinces/nations, and the result becomes more and more ugly. Aren't pandemics another consequence of those? Hollywood glorifies what sells (attracts many). Many feel, more or less consciously, surrounded by the masses, threatened by it, and react thru nihilism/Machiavellianism/...
