Fear leads to anger.

I'm such a Star Wars fan it's not even remotely funny. Something I came across last night that struck me though.

Love doesn't lead to the dark side. Passion can lead to rage and fear, and can be controlled, but passion is not the same thing as love. Controlling your passions while being in love, that's what they should teach you to beware, but love itself will save, not condemn you. - Jolee Bindo, Jedi Knight
