Am I going to tell them? No, I’m not going to tell them. I don’t see the point of that. As a doctor, you would not tell a patient if they had cancer.
— Michael ‧ The Office (U.S.)

Our reading
An editorial interpretation.
The speaker argues against telling others some bad news, seeing no point in it. To justify the silence, they compare themselves to a doctor who would keep a cancer diagnosis from a patient. It is offered as reasoning, though the analogy is the speaker's own contention rather than a settled principle.
