I feel like in the end Chief will give his life to defeat him.[/quote] Its unconfirmed that the Didact is not dead. So until then, he is dead.[/quote] Epilogue pretty much confirms that he is still alive. [/quote] I think that speech was something he said in the past, before any halo games.[/quote] Couldn't have been, the Didact didn't know about mankind's Precursor-given destiny to uphold the Mantle before he blew us back to the stone age. And when he did find out, we were in no position for the "reclamation to have already begun," (he doesn't even think it has begun when you first awaken him) and definitely in no position to be the "greatest threat in the galaxy." All of that could only possibly have been said after Halo 4.
