Leaving out important bits of reality almost always (eventually) results in shitty systems.
And "impacts on others" -are- huge bits of reality
Yet ALL our big problems exist as a DIRECT result of ignoring those same -huge- bits of reality.
Ethical considerations REQUIRE *emotionally understanding* the impacts of any given decision/system/product, war, etc….
Bottom line:
Develop your emotions and emotion based understandings of situations… if only so people won't cheer when you die.
