Bungie does not provide any restoration services so there is no way to resurrect a deleted character. Regarding the second question, the Forsaken DLC was $40 on its own in the US. To simplify the purchase options Bungie has bundled all the year 1 and year 2 content into one package for the same price. So that means you’re paying for Forsaken and getting all the year 1 content and the Forsaken Annual Pass for free. So while you don’t need the year 1 content you aren’t paying anything for it when you buy the Complete Collection.
