Did he not want out of the facility? Whether Ruth did it or not he was eventually going to get out. Its not Ruth fault Wendy let him get close enough to know Cartel dirtand eventually Wendy still handled it and put him safely in the mental facility. And Ruth got him back out on the streets, it's Ruth's fault.
