Looper, the Movie

Therefore, it is necessary to raise your own son to able to recognize him… So, what matters is who raises… and then he becomes your lovable son. Moreover, when you are able to identify the power of this love and, most of all, the horrible consequences of not having this love, then you find the real unconditional love… when you are able to help it in the most altruistic manner: when you save a child from not being motherless.
