At my alma mater they forced all of us to take a couple of humanities courses. They were actually the highlight of my senior year. I do believe it's something that's quite lacking in an number/outcome-based education that should actually strive to produce well rounded individuals that will-not-do-evil.

Alas, I went on to write code for a living anyway.
I loved probably 2/3rds of my gen ed courses back during my college years, but this was entirely due to an existing appreciation for the topics (history, literature, physical sciences), and around 1/3rd of them were worse than useless (I cannot remember a single positive lesson I took from them other than a sense of nihilism about the university's faculty hiring standards).
If the goal is moral development, few things will develop a person's morals than actually living and struggling in the real world, and college is NOT the real world. I have some half baked opinions about the degree to which university education produces a lot of adult children with arrested development due to an extended adolescence. If on the other hand, the goal is a classical liberal arts education, which I am quite sympathetic towards (at least in theory), I am skeptical that taking a handful of university humanities courses is the ideal way to accomplish this.
But I do agree ethics is a big one.
The course was a seminar on the 20th Century Politics of Japan with ~10 students.
Lots of great questions around the fall of imperial Japan and about what democracy means in Japan for example what would a socialist or communist Japan look like?
It was a wonderful course: great professor and a really fun small group learning and discussions.
