You know how, you don't need an explanation. But anyway, I'll do it.
People unregulated and left to their own devices do all sorts of selfish evil.
When they become powerful enough that involves mass death.
Think toxic torts and states killing in the name of exploitation like the Belgian Congo.
Take the example of big pharma and the history of hiding adverse events in clinical trials.
How about Big tobacco continuing to sell a deadly and addictive product knowing with certainty
mass death will result. And now of course, big oil is knowingly killing humans. With certainty
it will be visited on poor nations that can't ameliorate its effects. Get real. And yes I understand the
utility arguments and the hypocrisy of using such goods, but don't pretend it's not manslaughter just because
you can't name the individuals in advance if you do know with certainty what you are doing will kill people.
