Hawkman was a special case because they didn't want to spoil his death. Besides, Falk Hentschel had a good 8 episodes, even if Carter was no longer there. Castiel has enough importance to be a main cast. He's on the Supernatural Team so is pretty much a supporting protagonist.

But ultimately it all comes down to "Felicity needs to die" so theorizing up every possible means of her death. Felicity annoys me too, but knowing these writers they'll never kill her. At best is she leaves the show.
