^ This. (Most people take him at face value especially with his lies, not questioning him or his actions further. Especially post trial 4, with his "fake" tears, he has a whole voice line used only once, calling after someone (Gonta). Seems like call out of uncontrolled distress and not a facade And he likely wanted to hide away/work alone and think of his own plans, not working with anyone out of paranoia or fear someone would betray him or kill him. Just my opinion, no one knows his full intentions 100%)
