Do you ever think UU!Spoke sits down and just rethinks everything he's done? The way he's ruined lived even on accident. How he killed someone's daughter just for a stupid task, that he could have faked (not really, but thinking he could)?
UU!Spoke sits down alone at the fortress (before BAT started sending the spies on him) when Mapicc was out get materials, think silently about everything, sometimes it gets to a point where he ends up curling into himself and shifting down into his void form which is 2 feet tall. In the fortress, Spoke has made holes and hiding spots for him when people or life gets overwhelming.
He never wanted to hurt people before the mafia event. He just wanted to have fun and goof around. Pain wasn't something he meant to start. Maybe that's just the way he is.
Mapicc has a few times found Spoke in these moods and comforted the void creature by just sitting there with him and waiting patiently for Spoke to come around, so they could decompress together.
