Locke's LOST his mind

Ok, so what the heck is up w/ Locke? He's completely obsessed w/ pressing buttons! At first it was in the hatch where he obsessed over entering the code. Then he lost his mind and didn't press it and caused the hatch to blow up. Last night he presses buttons on the computer at Flame which started a self-destruct sequence and left Flame in, well, flames. He's like a two year old! I bet he lost his ability to walk because he came across a button that said "Don't push or else you'll lose the use of your legs" and he pushed it. So to recap, Locke likes to push buttons and blow things up.
