People destroy their own lives if it was not meth it would be something else. It's just s faster way to do it. Cigarettes, poor diet and exercise habits ,general unhappines all point ultimately to a hole in someones thought process that they are unwilling or unable to deal with. Unwilling usually IMHO. It's easier to be a victim because there are so many around looking for the same break for their behavior and choices in life. If you traced back to the cause not the symptoms of why the person ended up floating in the river it will personal choice. Accident or not.
