“My mistake is about to land on a junior person and I could let it.”

The error was yours, but the blame is drifting toward someone with less power to defend themselves, and you could let the current carry it. They'd take the hit; you'd stay clean. It's the coward's version of doing right in the dark — using the shadows to push your failure onto someone who trusted you. Owning your losses matters most exactly when someone weaker would otherwise pay for them.
