Look, I will give my two cents, but promise me not to go "reeee pedo defense" until you finish my post.
I think, his behaviour had more to do with the company he kept. All his associates were somehow involved with that shit. Ruby was into age play, Puk jerked off to Tracy Lord "cuz it was cool", other guy who had account here claimed in DMs to date 14 yo when he was 19, Neil was hentai obsessed sperg and Jetrex, well, you know what he did. Boon had some shit too, but I fail to recall what it was at the moment. So talking to all those people made him think that being into children is cool and edgy. For the most part, I think he watched loli stuff since it's easy to find.
Claiming to be into this was more of his way to get a reaction from people and he was too retarded to see the long term consequences. You can notice in streams with him how he is trying to dial it further when he sees people getting mad at him. Also, none of his claims about working at a school or having CP were never confirmed, the latter wasn't confirmed even after the police was involved. (I skip I'm touching a child since the only source of this was Bryan and he failed to show any receipts, so it was bullshit)
So yeah, I think, for the most part he was just a sperg who used pedo shit as the means to look edgy and get people angry, thinking that it makes him own them somehow.
