Don't forget:
Kill thousands for profit -> no need to care, move along, no one is at fault and nothing of importance really happened
Kill one that is responsible for the former -> you must preface your discussion with hundreds of references to murder being bad, and clearly and unambiguously condemn the monster that did this
Humans really do have a bias where doing something small-scale but visceral causes horror and outrage, but doing 1000x that harm by building slow and boring bureaucratic machines of death is not noticeable because, after all, the machine isn't literally putting a gun to the face of the victims, so it's all fine.
