The dark side is emotion, Bane. Anger, hate, love, lust. These are what make us strong, Peace is a lie. There is only passion. Your passion is still there, Bane. Seek it out. Reclaim it.
Evil is a word used by the ignorant and the weak. The Dark Side is about survival. It's about unleashing your inner power. It glorifies the strength of the individual.
The Sith were the sworn enemies of the Jedi and the Republic. They sought to wipe us from existence; they sought to rule the galaxy. (...) A Dark Jedi, on the other hand, has much smaller ambitions. He -or she- thinks only of himself. He acts alone. The ultimate goal is not galactic conquest, but personal wealth and importance. Like a common thug or criminal, he revels in cruelty and selfishness. He preys upon the weak and vulnerable, spreading misery and suffering wherever he goes.
...Des felt a familiar feeling in the pit of his stomach. All soldiers felt the same thing going into battle, whether they admitted it or not: fear. Fear of failure, fear of dying, fear of watching their friends die, fear of being wounded and living out the rest of their days crippled or maimed. The fear was always there, and it would devour you if you let it. Des knew how to turn that fear to his own advantage. Take what makes you weak and turn it into something that makes you strong. Transform the fear into anger and hate: hatred of the enemy; hatred of the Republic and the Jedi. The hate gave him strength, and the strength brought him victory. For Des the transformation came easily once the fighting started. Thanks to his abusive father, he'd been turning fear into anger and hate ever since he was a child. Maybe that was why he was such a good soldier. Maybe that was why the others looked to him for leadership.
