You're missing how the story is coming together. I read an interesting theory that uses bits like the intro song "i live among you, well disguised" and the purposeful omissions of Paul Woodrough's life (his dad, what he did after Blackrock) to show that HE IS THE BIRDMAN. And his dad is Caspere, the guy in the beginning. He is the one doing it all, but he's so messed up that he doesn't remember doing any of it. He and McAdams are some of the children that were used by the pedohpiles in the first season that Woody and Rust discovered. Boom. Let that sink in and see if it unfolds this way.
