Umm... you better look up armchair psychologist again; that is about unqualified people playing psychologist.If you had any credentials in psychology, it would still be armchair psychology because you didn't actually spent any time with him or examined him.
That's literally the dictionary definition of armchair psychology. It's worthless commentary because you don't actually know him and are just going by small snippets of interviews - where he could be trolling, playing a character, etc.
So let me explain it to you. Making a diagnosis, treatment plan, or providing individual/group psychotherapy requires seeing someone in person (or a lot on Zoom) and is a thorough process. However, there is nothing wrong with making observations about people's behavior, especially when you already have some of the kind of collateral information you would need in a treatment setting- such as his family background of being abused by his father. It doesn't mean I am right, but the behavioral observations are more credible than yours.
