Egoism was not there in early days.all wars of yester years are the balance sheet of Egoism.That days girls used to get married at 10 and boys 13 or 14 and they used to indulge in physical relation in teenage it self ,is it ok.That time also slavery and untouchability existed in world wide.a 65 old dalit can be trashed by a 15 year old upper caste,is it the respect for elders.
