You are in a difficult situation. Your employer is a Corporation, which is solely focused on maximizing profits. Corporations act exactly as psychopaths, no guilt, no shame, people, the world are disposable in the attainment of their goals. As lawsuits are expensive, they cannot endorse employees using lethal force at the work place. Employee’s killed by criminals are a law enforcement matter, the burden of which is carried by society, so in the cold logic of a financial statement, dead employees are cheaper than dead criminals.
In fact dead employees may be very profitable. You may not have heard of dead peasant policies, but a large number of corporations are taking life insurance policies on their employees, with the corporation as the beneficiary.

So you are between a rock and a hard place. We all need an income, but your employer may have a profit motive in making you dead.
You have to decide whether your loyalty to a Psychopath extends to the loss of your life.
