Look up the details of Robin William’s death.
I did. Carradine wasn’t trying to commit suicide with his self-pleasuring dangerous sex act, but it happened. Williams WAS trying to commit suicide because he had the ghastly Lewy Body Dementia (although that wasn’t confirmed until the autopsy - he didn’t know what was destroying him). I don’t even wish to ponder the terrors he was experiencing that led him to make that decision to find a lasting release from it.
