dane felt that feeling coming up from deep inside him , that determination that he would never give up , that he would never surrender , that he would keep fighting to his dying breath , and with it came that other feeling , the one that frightened him to the core of his being : that rage , that killing rage , that he was afraid that if it ever completely escaped the iron hold that was on it , he would kill , and kill , and keep on killing until there was no one left alive around him .
