In the first Scream movie, what was Stu's motive for the killings?

Stu doesn't really seem to have a motive, he's just nuts and along for the ride. Only Billy has a reason for what he does.

Well in the first movie of Scream Sidneys Boyfriend and her friend teamed up and killed people but there primary mission was to kill Sidney because her mom slept with her Boyfriends Dad who split up his parents and Caused him some mental Abuse unfortunately he could not take the fact that his dad was a sleze and in the Second movie the person who killed everyone there was Her old boyfriends Mom who was the master plotter of the whole movie and in the Last one it was all Sidney's

long lost brother which she knew nothing about and he tried to kill her because he was jealous of Sidney he thought that she was the favorite but there all nuttier than squarrell sh*t lol i cant wait until the 4th one come out but i dont think they can get the whole orginal cast so it will probably be lame plus they will also try to make it in 3d i hate 3D it messes up the whole film sometimes they just want to make alot of money but they loose the quality of the movie u know some movies shouldnt be in 3D hope this helps and have a good day.

Peer Pressure...Hes far to sensitive
