You are, in fact, wrong. He believes that God has been speaking to him since he was a child and that he is fighting against the Devil. Not metaphorically, the literal Christian Devil.

8+ years after Sandy Hook, during a deposition, under oath for a defamation lawsuit about that tragedy, he doubles down and says that he still has doubts while constantly rambling about how this is all a plot by the "globalists" to take him down, which he makes clear includes the presiding judge and the plaintiff's lawyer.

There is a reason his ex-wife of 8 years said he "is truly mentally ill", that "he should be protected from himself and others", and that "he lives in his own universe, and he is a very — in my opinion — delusional man.”

Being a grifter and genuinely mentally unwell aren't mutually exclusive.
