PsExec is a tool, not a criminal. A tool can be used by a criminal or a tool can be used by a law-abiding person. If a criminal uses a tool, does it make sense for the law abiding person to stop using that tool? What impact would this have on the criminal’s behavior or usage of the tool? For example, if a criminal used a car as the transportation mechanism to rob a bank, what would it solve if you then stopped driving your car?
