I bolton, you zeroed in a theme I see in play in the story: Control. At the beginning, Arthur attempts to control his behavior, but as evidenced by his uncontrollable laughter, there are instincts within in psyche which prove to be beyond his control. His rage and his growing propensity toward violence is, I think, a reflection of his shadow, and in the end, instead of fighting his shadow, he embraces it. In a sick way, this is how he aligns himself with his authentic nature, so in effect, his Unity state at the end is becoming his Shadow Self. The fact the universe responds as it does — cheering crowds and acclaim — reinforces his sense that by ceding control to his shadow and giving himself over to his rage and violence, that is where and who he is supposed to be. The presumed murder of the social worker in the Denouement confirms that choice.

So yes, he has given up attempting to “fit into society,” indeed, to control his darker impulses. Instead, he embraces his shadow and becomes one with it.
