Yeah, but sometimes "if your negligence kills these people we will put you in jail" is exactly how you get people to pay attention. The vital part is closing the loop.

I disagree. That's not how it works. Responsibility is a product of education and environment, not a product of fear. Fear makes people avoid responsibility, not assume it.

Fear is a phenomenal backstop to responsibility, and in fact most aviation safety relies on the fact that pilots don't want to die.

Paperwork should be regularly audited and discrepancies investigated. The other nice thing about fear is that it should be very specific - people should know exactly what they have to do to not feel it.
