Yes it does make him a monster who makes me wonder why anyone wold be upset that he ended up in jail (presumably for life). The thing that's upsetting is that they changed Cliff's personality so drastically to the point where he wasn't recognizable as the same character anymore. The Cliff we knew from the real Dallas would never have done that to his daughter. Cliff wasn't a murderer. Neither was JR. There were some lines that neither JR nor Cliff would cross even though both were capable of doing some pretty awful things. Since they did change his character though, what is upsetting about Cliff getting what he deserved for blowing up the platform with people on it including his pregnant daughter?
