[quote] And if they felt like they absolutely had to have the Didact as an antagonist in Halo 4, they could have easily found a better way to do it than making him out of character and evil and doing his evil deeds because he hates humans :/ [/quote] Being mind--blam!- by the Gravemind into becoming a genocidal madman, having his wife betray him (due to his madness) and then being locked up, conscious, alone for 100,000 years with nothing but his own thoughts will do a number on anyone, no matter how good, noble or well-meaning he was in the beginning. Didact is a walking Greek tragedy, a great hero who was wise, only to fall victim to circumstance and become the very thing he sought to destroy. In many ways he personifies the Forerunners' fall from grace, as the once noble empire succumbed to corruption and racism.. You're right. He is acting out of character, if you were only to look at the context-less window of time the Halo 3 terminals give us (themselves being told by someone who isn't exactly an unbiased character). And that is literally the point of a Greek tragedy like him. Halo 4 doesn't do a good job of going into those details--mainly because doing so would ruin pretty much all of Didact's arc in Silentium which hadn't come out yet and result in a game that was more than half expository dialogue--but his story is there.
