Why the violence? Because left to its own devices life would never produce love, it would only lead you to attraction, from attraction to pleasure, then to attachment, to satisfaction, which finally leads to wearisomeness and boredom. Then comes a plateau. Then once again the weary cycle: attraction, pleasure, attachment, fulfillment, satisfaction, boredom. All of this mixed with the anxieties, the jealousies, the possessiveness, the sorrow, the pain, that make the cycle a roller coaster.
