" I like fighting and I like killing,” Boomerang said, and he laughed. “And when I kill I feel good. So your theory’s all shot to hell.” “But that blissful feeling is only temporary. Kills are like drugs. You need more and more to get that same feeling again. Today it’s one kill. Tomorrow two. Next week it’ll take a dozen. Not only is there no end in sight, but after a while you forget why you ever started. Your need for relief, rather than your intellect, takes over—and it is insatiable. "
