No, should have been 20, it IS a dlc. And free to all season pass holders or anyone who bought the collectors editions in destiny beta. Why it's not? Luke Smith can tell you why not.

It's an expansion, twice the size of DLC, so yes $40 is a fair price.

Shouldn't be free to season pass holders. The season pass was advertised as covering two dlc packs, the dark below and house of wolves. A $20 dollar price tag would be a good debatable point though. But compared to the first two DLCs, it's bigger and offers more. That gets into a convaluted discussion on what is worth what price.

The first two should have been 20$ if this is worth 40 maybe even 10$ for the first 2 how was worth 5$
