only few can understand leland character and and to do that u most likely be inborn to see both side of life and and to face this reality be very hard and can lead some few to bad act ( like leland character do ) but for such sad and real reason that his intention be good and in the sense that the intention to save another from physical or mental ( in this case ) pain over long time . and it be really sad how mostly everyone in this movie make mistake in it and but the one character to make one through good intention be kill by it . the lesson of this movie be for the unique person to see and realize and face and make right of the real life situation u see and to make right and or inspire one who can make right of a wrong situation . but before that . u have to see both side of something and rationalize it for the sake of long peace and and tranquility of all human life . aka don not be ignorant .
