[quote][b]Posted by:[/b] Maximus Decimus All I know is that Silentium has a lot to explain. Specifically why Didact loses his -blam!- and all of a sudden wants to exterminate humanity. His hatred was never that great in the books. And him having to meditate for 100,000 years over what has happened isn't a justifiable answer in my opinion. What he's doing goes against the principles of the mantle. [/quote] You know that this was all explained in Halo 4 and the Terminals, right? Allow me to quote things for you: - "The [humans] must be sent home and taught to stand with the galaxy, rather than rail against us and take what they desire. the Mantle shelters all." - "The humans' actions threatened the galaxy, yet we have treated them as the Mantle requires. Their punishment was just." - "They are closer now to the animals they behaved as." - "The humans were not meant to protect others. The Mantle of Responsibility for all things is ours, and ours alone." - "My finest opponent, the Mantle accepts all who live fiercely, who defend their young, who build and struggle and grow, and even those who dominate - as humans have dominated; cruelly, without wisdom." - "They took the Mantle of Responsibility upon themselves, and in so doing, they brought the sickness to our shores." - Faber: "So you agree that Halos are our only solution." Librarian: "I do." Faber: "And your husband?" Librarian: "My husband has a different opinion on what steps to take against the Flood." - "Didact, if the Composer is our final hope to defeat the Flood, no Promethean would resist." - "Humans, your kind brought the Flood to our shores. Now you will aid in ending its threat." - "Your pets have a nobler purpose ahead of them." - "Humanity's loss of biological form will serve as final payment for their crimes." - "We squander eons in the darkness while they seize our triumphs for their own! The Mantle of Responsibility for all things belongs to Forerunners alone." There is plenty of exposition on the Didact's motives and 'hatred' of humanity in the Terminals, his transformation from providing humanity with the chance to live but in a degraded form, treating them "as the Mantle requires", to growing desperate in his need to defeat the Flood. Now let's move to the Librarian's dialogue in the campaign when she speaks to John and see how this connects. - "Weakened from our conflict, we were no match for the Parasite which pursued you." - "The Forerunners made plans for a final great Journey, but the Didact refused to yield our Mantle of responsibility." - "Such moral concerns faded from the Didact's attention." - "The Composer would grant the Didact his solution and his revenge." This shows a clear transformation of character. He grew obsessed with the idea that the Composer was the solution, which is also mentioned in Silentium's official description - that he is in a conflict with his wife over the keys to a solution. He believes he is fulfilling the requirements of the Mantle by composing humanity, their "final payment" for what they did to the Forerunners. [Edited on 01.05.2013 3:56 PM PST]
