I always knew he had control issues with women. So he's shown behaviors that indicate he might have no problem murdering or torturing real women- by proxy perhaps?
Now you know why he was in a show called Two and A Half Men- becuz he cant deal with women! Unless they are ultimately controllable as in being inanimate objects or probably in a coma or something of that nature.
Love the part about disposing of the plastic doll body parts with the drama and zeal as if it were real body parts. Practice makes perfect!
