The Force
The dark side of the Force is used by the Sith, the bad guys, in the Star Wars movies. Sith have a lot of anger, fear, hate and aggression. The dark side of the Force gives the bad guys powers that the Jedi, the good guys, do not have. For example, Darth Sidious is able to shoot lightning from his fingers. The dark side can seem stronger but that is just because a person who uses the dark side of the Force does not have to hold anything back, he is not restrained.
