Such egocentric individuals do not understand the importance of generosity and selfless acts towards their human souls. Their sole focus lies on fulfilling their own needs, mistakenly realizing the hurt they inflict upon others. Fundamentally, such individuals perpetuate a society lacking empathy and compassion.
