When I taught design I ended one of my courses with a lecture and discussion on ethics, and I'd like to think I was pretty even-handed. One common issue that most young designers encounter is being asked to implement dark patterns that improve the company's profits at the expense of the end-user's well-being. The goal of that lecture was not to tell students what is right and what is wrong but to get them to think critically about the effects of their decisions on end-users, customers, society, and the planet. But those answers are different for everyone, for example in my case I was more ethically comfortable working on US military projects than projects involving advertising, social media, gambling, or other forms of psychological manipulation.
