So you're proving the pointI don't know, if that was my mom being brutally attacked I would want him charged to the fullest. On the other hand if he do suffer from those mental disabilities he need to be in a place to get him some help.
If he had the mental acuity and capacity to know what he was doing then yes, throw him under the jail
That's clearly not the case here. Granted I would feel the same way had this happened to my mom but I wouldn't want him to spend the rest of his life in jail. It was just an unfortunate situation all around and it feels like he was failed at so many levels
