interesting you say SLE because while i can see it in the last video, my first thought after watching the first video was IEI gone bad.
what i mean by that is basically that there was an intentional dramatic flare in his speech and certain metaphysical way of describing/questioning things. the tendency to raise a question (the answer which he assumes is expected of the audience), then answer it, revealing that he actually believes the opposite of what is expected, is apparent. while i would imagine that this tendency is due more to manic/psychotic behavior in his case, i would be interested to explore the possibility that this is either: a.) an example of Ni/Fe in dire need of dualization (and/or perhaps as an INFp victim learning only to victimize others through unhealthy interactions largely beyond his control) OR b.) an example of Se/Ti Ni-dual seeking in twisted fashion (Ni seeking as manifest in the poetic, rhetorical, metaphysical flare).
