What if the return current goes through a different wire that was used as a quick fix for some wiring problem someone ran into 50 years ago?

That is potentially quite dangerous, especially if that different wire is sitting on a different breaker.

Standard breakers only interrupt the hot side. Old wiring is full of shared neutral ghosts. It's not great but it isn't as dangerous as randomly dissipating the current throughout the house.
