After he took 3 pills in Chapter 33, all his internal organs ruptured....that would've include his brain.

He was always stupid, but what if his brain never really regenerated to it's full capacity ever again? This one single action might be the sole reason he never learns. Very gullible and willing trust pretty much anyone.
