I think that you might be interested in the Milgram's Obedience Experiment. The experiment tested the effects of subjects following the demands of a trusted official no matter how barbaric the commands were. In Milgram's findings, few subjects possessed a demonstrative level of compassion and pity, and these individuals represented what Milgram did see as a more "evolved" human being. The test subjects that refused to continue the experiment when they observed, or believed to observe, another human being suffer represents the compassion and pity that he did not find in a majority of his test subjects. The Milgram Experiment raises questions as to how rare an innate personality trait of compassion and pity are within human beings. This would help to illuminate the idea of how such traits are characteristics of a more "evolved" human being. The Milgram Experiment might be something for you to examine as it truly highlights the importance and rare traits of compassion and pity within human beings.
