Pro-social behaviour is very similar to _________.

Altruism 

Throughout the world, doing good to others and being helpful is described as a virtue. All religions teach us that we should help those who are in need. This behaviour is called helping or pro-social behaviour. Prosocial behaviour is very similar to ‘altruism’, which means doing something for or thinking about the welfare of others without any self-interest (in Latin ‘alter’ means ‘other’, the opposite of ‘ego’ which means ‘self’). Some common examples of pro-social behaviour are sharing things, cooperating with others, helping during natural calamities, showing sympathy, doing favours to others, and making charitable donations.
