if humans never fought it wouldn't be heartwarming to see different kinds of people come together for one cause
example: there was a man who i think was atheist and was doing something such as flaming christianity or just saying what christianity is all about and then he found out he had some disease and couldn't pay his bill and these christians he was flaming paid for his bill. he then said that these people were real christians, helping other people out. it's more heartwarming with all the exact details...
