The cyborg simply cannot comprehend the human logic of the youth, since the cyborg operates and relies on a level of computer logic. After John orders the terminator not to kill anyone, we notice the cyborg shooting a police officer in the leg. The cyborg does not feel empathy towards the police officer who lies on the ground crying in pain. He views a life as a statistic, where acts of benevolence do not exist in his files. He was not programmed with respect of human life and therefore cannot understand anything outside his programming environment.
Human beings rely on history to define their inner selves.
Their experiences and memories shape, mold and gives them a sense of individuality. Once appreciated for it's splendor, these experiences give human beings a sense of belonging. This is one reason why cyborgs will never be human. As human beings we make mistakes and try to learn from them. Cyborgs, however, lack human emotion, think objectively and considers failure to be not an option.
