One such was, according to him, an occasion when "they handcuffed him, drugged him, put him on the bed".
Now despite this, I also don't agree with just handwaving the discussions then, like, oh he's mad, so everything strange thing he does must be because of that. I think that it's perfectly valid to be mentally ill on one hand, and a huge asshole on the other. A strong motivator for sure, but illness is not a character trait, mental or not.

On a second thought, I'd also like to add that the human psyche is not a solved problem. An average outside observer absolutely can't tell if an out of place thing is because of illness, or something other than that. Even the "standard" way to recognize and classify mental disorders, the DSM-5, changes from one edition to the other.
