Re: "Why does Nick lie so blatantly like that?"
Nick knows that he won't be able to convince normal people that he's a good man, so he's stopped trying to even engage with normal people at all.
Every stream, tweet, and locals post he makes now is exclusively made for his few remaining retarded simps to convince them that he's innocent with blatant lies so he can have his little hugbox that pays him superchats to say "you're such a victim Nick!" and maybe flash their droopy wine aunt titties.
Nick's a hedonist that requires constant instant gratification. Why talk to the people that tell him the truth he's a bad person, it's his fault, and should fix his life, which makes him feel bad when he could retreat into his hugbox where they lie, coddling him and agreeing that the government is bad and nothing was Nick's fault, which makes him feel good?
