The thing is, Kurata's arabitions extending from something so simple DOES work. o_o Hatred isn't always some complex thing; all he saw was something that in his eyes, he was unable to stand up against. And meanwhile, here was Daimon Suguru, who not only dealt with them, denounced Kurata's concerns and eventually became a legend among them. It was a corabination of personal insecurity and fear, and it boiled down to a selfish desire of wanting personal glory. By the end, he was ranting more about his own brilliance, and surpassing his rival, than his hatred, which was the real core of it.
And as for using digimon in his plans... well, people who hate and fear something usually pursue ways to dominate and subjugate the things they hate and fear. He didn't ally with digimon, he controlled them and did horrific experiments on them and bonded them with people. That's not liking digimon, that's exploiting them and using them against their own kind while twisting them into horrible monsters.
