As the Baltimore philosopher Butchie put it: "Conscience do cost."

Feeling good makes people happy. What's measured to produce that feeling is the outcome of the am-I-good thing in your brain's evaluation of whatever you did, and Goodhart's law is always in effect. You can pay the cost of being good and earn a good evaluation—or you can do whatever you want, enjoy the rewards, and trick the am-I-good thing into always saying yes.

Since the latter method makes you feel good cheaper and faster, I'd expect it to be fairly common. In my experience it is.

So it's really option 3: do bad things and don't feel bad, with views on right and wrong aligned suspiciously precisely with your personal interests.

(Hopefully I've made it clear I'm not endorsing this, just describing it.)

Yes, it was clear that you aren't endorsing this. However, people who behave badly usually have to face consequences from other people. The selfish person is rarely just selfish at work. They take it home to their families and live with the consequences of pretty weak relationships. The greedy are never satisfied with what they have, so they're in a constant state of wanting. That's a pretty unpleasant place to be.
