Likewise, mental illness isn't the only possible reason for those characteristics.

He doesn't have to be mentally ill to be an arrogant, entitled, self centered, self important asshole.

Seems like "affluenza" to me.

Unless you're willing to assume mental illness for everyone with those qualities i see no reason to shoot down the idea that he's probably not mentally ill.

Personally I don't see anything he does that supports the mental illness conclusion. I see a lot to support the arrogant, egomaniacal asshole conclusion.

Fortunately I'm not a Ye Stan so I'm not blinded by fandom.
