no moral guarantees

The correct decision, given a trolley problem, is to switch the track, then wonder for the rest of your life whether you made the right decision. Anyone who could confidently switch the track and then never think about it again is a sociopath, as is anyone who fails to switch the track and believes his decision entirely exculpates him. Trolleys and certain deaths don't reflect moral decisions in the real world. Not only do you not know precisely the consequences of your actions ahead of time, you certainly don't know the consequences of the counterfactual. [...] The universe offers no moral guarantees. We make decisions, and live with them, and never know the results of the decisions we didn't make. This is the best we're offered. -- Andreas Schou
