Morally is different but it's also the gist of the problem. Inaction makes you exempt because you didn't took part.

People choose inaction all the time. When we see a bully abusing a colleague... A homeless person on the street... A car aciddent. This is the metaphor.

But it's different. Facing a bully is more like jumping in front of the train to stop it.
