Engineers talking about engineers that should act ethically is good, but self limiting, and even self defeating. For every engineer that builds a terror weapon, every architect that builds a McMansion, every chef that brings out unhealthy food with not fresh ingredient, every school district that fails at educating kids adequately, there is someone with a checkbook that decides who/what gets paid for a goal. All bad or unethical product is ultimately possible because of someone writing the checkbook. If one or even all engineers of an organization disagree and leave due to ethics, the checkbook writer will just go out and hire next batch of engineers. In the fictional story or Star Wars, someone had money (or credits in Star Wars universe) to put the stormtroopers, Star Destroyers, Tie Fighters, a planet with beautiful tropical islands with sandy beaches and competent engineers (but often incompetent security force) to work at building the Death Star. Sure the Emperor has the force to get it done, but in our life, someone gets to dictate what gets built with a checkbook. So, discussing ethics in engineering is great, but even more important imho is, who writes the checks.
