Sooo many will tout something along "fiduciary duty to shareholders" to explain why evil must happen. Just search for it in comments here on HN, and you will see it again and again, as if everyone's hands are twisted.

You are confused. Yes, lots of people say that here, but the intention is almost never to justify immoral behavior. Rather the goal is to delegitimize capitalism by blaming it for the immoral behavior.
