Although Ainsworth didn't fully dismiss the plausibility of the theory he made, he didn't let it get to him as he was too weak to solve it.
If his theory happened to be false, then that would be for the best. Otherwise, he would have another reason to surpass the SSS-rank Awakeners and reach a power no one on Earth has ever reached, to solve the mastermind behind all of this.
After Ainsworth made his theory, he then shifted his attention back to Howard, Judy, and the survivors.
They all had become zombies and interestingly enough, their intelligence and personality when they were still a human were retained due to the Hive Mind preserving it. Of course, the preserved intelligence and personality were already modified by the Hive Mind to be loyal to him.
From his estimation, only Special Zombies would be able to retain human characteristics but not only Kyle from before, but even the new survivors he infected still retained them.
