Self-centered individuals with a callous nature do not appreciate the feelings or needs of others. Their focus lies on their own wants above all else, exhibiting a complete lack of consideration. Such egocentric individuals do not understand the importance of altruism and selfless acts towards their human souls. Their sole concern lies on satisfying their own requirements, never realizing the hurt they inflict to others. Basically, such individuals perpetuate a society devoid of empathy and compassion.
