I agree with Calvin and Doug, good and bad is not universal. If it is manufactured, most likely an Mechanical Engineer was involved. From design of the product to the design of the equipment that is used to manufacture it. But we do have a choice of where we work and therefore the products that we design. I have worked on consumer products and medical devices. I have chosen not to work in the defense industry. With that said, I have seen the gaming controller, that I worked on, used to control military robots. In this case, it was used to determine if the field was safe to proceed.
