I agree, at best mental issues seem to be at work, to put it mildly. Nothing seems to have changed in that regard either, not even slightly. I still think though a better description of his character can be found in
Łobaczewski's work. At least he was diagnosed in court to have a "narcissistic personality disorder" and in fact I think that this diagnosis is probably not far of the mark. I would say a great deal of paranoia and schizophrenic thinking seems to be involved too. I'm also not sure if he means the same things as ordinary people do when they talk about "justice" and "changing the world for the better"... Some kind of schizophrenic charactopathy might be involved. Also notice, that basically Jones never manages to really have a discussion with Rogan or anyone else for that matter (from what I've seen so far). If you observe it closely, it seems like he is constantly in his own head and doesn't really engage in the conversation as normal people do. It seems like for Jones there is always his own film running in his head with very little ability to accommodate and really understand outside perspectives.
I do think by now though that he is really into and believing the things he says and not consciously misleading (I could be wrong though). He just can't help himself mentally and thus he is a very good candidate for manipulation from other nefarious agents. You can also notice that he constantly slightly misreads what people actually say, into what he thinks they said and did, and by doing so, he slightly but profoundly changes what actually happened in his mind, which then gets passed on to others, in an altered, removed from reality kind of way.
Yes you understood that correctly, at least according to his own statements and other data. See
here,
here and
here for more information about that.
Perhaps, but if so, he seems to have lost the plot a long time ago unfortunately.
