"should the spoiler category only go under episodes that haven't aired?"

No. This is why: Some people might not have seen the episode the night it aired. If they missed the episode and went to the episode page, then the information on the page would be considered a spoiler to them. Also, if somebody lived in a different country and the episodes aired on different dates, and they went to the episode pages everything on the episode page would be a spoiler to them. The spoiler category lets people (who haven't seen the episode) know that there are spoilers on the page.
