Last year a young girl with disabilities was about to be harassed by two boys on a neighbourhood playground, when another a young man who heard what was happening came over and stood between the girl and the two boys. He stood his ground until they backed down.
The young man is a Christian, and "knew what they were doing was wrong". He is also 5 years old; a kindergarden student at a local school. He was recognized by his school for bravery. I know the story because the girl is my daughter.
