Light Side:here is no emotion,there is peace.There is no ignorance, there is knowledge.There is no passion, there is serenity.There is no chaos, there is harmony.There is no death, there is the Force
Dark Side:Peace is a lie. There is only Passion.Through Passion I gain Strength.Through Strength I gain Power.Through Power I gain Victory.Through Victory my chains are Broken.The Force shall free me.
One is telling you emotion is bad for you to have but without it you can be unmatched with mind like abilities. The other says emotion is key to power and without it your nothing. Which do you think is better?
