People are born with moral guidelines already built in.

These conclusions were reached by Japanese psychologists in the course of experiments with eight-month-old children. The kids were shown on the computer screen an animation with two multi-colored balls. One of them offended the other. In another video, a stone was falling on a ball. The children were able to control the computer system using eye-tracking technology. When they had the opportunity, they sought to punish the aggressor ball and drop the stone on it. It turned out that infants who still cannot talk were punishing the antisocial aggressor. This indicates that humans may have developed a tendency toward moral behavior over the course of evolution.
