Is Hasan the final boss for Destiny?

We have seen Destiny go against many people, and many people go after Destiny. Usually it ends with those people being irrelevant and casted out from whatever bubble they're in.

But is Hasan the largest creator that Destiny had a direct conflict with? Is Hasan on his way to crash out? Or is he too big for that? On the other hand, I don't see Destiny having more than temporarily set back if Hasan was successful with his attacks, so I think Hasan has more to lose in a sense, but he definitely has more reach so far.

Where do think things will go from here? Will one of them be a clear victor or will it just be a back and forth until the end of times?

I'm definitely on Destiny's side here, but that's irrelevant.
