I'm sorry mountain bear your logic doesn't hold up.
The individual is licensed i.e. approved to standard. With that licence comes responsibility and accountability. If he was forced at gunpoint to do such a bad job then yes the company should also be accountable.
You are accountable for your actions and in fact EASA regulations are specific and I would imagine FAA as well:
(c) Any person or organisation performing maintenance shall be responsible for the tasks performed
Now you need to understand aviation regulations before going on about company agent nonsense.
An airline must make use of approved maintenance organisations, those maintenance organisations must employ licensed staff.
Licensed staff must ensure the work is performed to a standard before certifying for such. This is the basic ICAO format.
What you are advocating in your moment of madness is that nobody is responsible even when they have completely failed in their individual task. A task that the regulation says they are responsible for.
