 PLOT: In Dead Zone, Garlic Jr. avenges his father by trying to kill  Piccolo, and therefore Kami, at the beginning of the movie. Yet  Garlic Jr. wants to get the Dragon Balls to wish for immortality.  Killing Kami/Piccolo will cause the Dragon Balls to vanish. Because  of this, Garlic Jr. should have gotten immortal life BEFORE  attacking Piccolo. Its also possible Garlic Jr. didnt know killing  Kami would destroy the Dragon Balls, but this is unlikely as his  father tried to become Kami, and therefore Garlic Jr would therefore  have knowledge of the subject.
