Maybe we can settle on him being so6?
Sx1 seems to enforce social rules, archetypical 4L, they get bloody intense over rules, but seem to are about the people around them and probably won't bother with people on the opposite side of the world.
I think sol's issue is rather his own ego, his own image, which makes sense for me since he openly talks about all “mystical stuff” he participates in, openly talks about never having any real opportunity to be romantic with women despite his old age, complaining on how is he being wronged by everything, etc, regurgitates shit to drag other people down, and never really displays or puts a strong effort into showing as to why he is right(reasoning + evidence) which is something everyone does when they genuinely want to share what they think is right. So his own behavior and claims don't seem to add up, especially with how his own issues alone are not socially acceptable if now seen as weakness for a man to be so archetypical effeminate in pretty much most societies.
Again, we can't also expect him to fully display how he feels in his own second language, but his actions seem that way to me. I don't see the high volition in him at all, just the will to harass other people and be annoying.
But again he doesn't seem to fit so4 or sp4, but sx4 which is very different from the rest on their own.
Sexual Four: HATEThis subtype is different from its fellow Fours because they are able to take their Anger on a walk and do so with a strong vehemence and righteousness. We could say that the Four’s normal behavior, crying, is substituted with shouting and violent criticism. While we see the Social Four’s constant shame, we see the Sexual Four as a shameless character. They are very loud and insistent on their demands. They can be very annoying and feel a strong sense of rejection from the world. And the more they feel rejected, the more they complain. They are Intensity in its pure form, competitive and arrogant.
This is the subtype we could describe as cutting off people’s heads due to their almost Eightish sadism. Some authors, including Ichazo in 1969, refer to them as the Hate Four. They also have some similar aspects to Sexual Sixes, because when they smell fear, they jump into action without being paralyzed. Even physically they can look like these Sixes, sometimes looking strong enough to survive a bomb attack with a strong chestplate.
