You can't paint a proper moral picture of a situation by imagining your responsibility is compartmentalized and that you operate in an environment where others will or at least could in theory operate ideally.

Such an approximation must as part of the moral calculus be incrementally replaced with a more accurate picture that takes into account the actual foibles of your fellow humans actually behave.

If given how people actually behave evil or injustice is done that is your fault. Not partially your fault, your fault guilt doesn't divide it just multiplies. You are I think bound not to do the least you can do but rather the most you can do. The best idea I've heard in this thread is to always show multiple results with no indication of which was higher priority. Force a human into the loop.
