"Anger, Fear, Aggression, the Dark Side of the Force are they. Easily they flow, quick to join you in a fight."
- Yoda, The Empire Strikes Back
Easier, more seductive, but
not more powerful than the
Light Side of the Force.
Luke Skywalker almost gives into the Dark Side once or twice, especially during the final confrontation before the Emperor. It gives him a quick boost of strength that allows him to overpower
Darth Vader, but he gets himself
under control before destroying him.
