Weird news - Robbing missionary, getting beaten up

This is the kind of behavior that police forces are always in 2 minds upon. If you are set upon by 2 robbers who have a gun, fighting them can be dangerous since one does not know their state of mind. They could be desperate and liable to use the gun on the person they are robbing, and a simple robbery could turn into a tragedy, a murder.
However, when something like the below case happens, people are liable to applaud the person who defeats the robbers, such as the missionary in this case. He was picked on by 2 armed robbers in Brazil, and fought back, disarming them and sending them on their way (link to article):

A newly released dramatic video captures two would-be robbers in the streets of Brazil being undone by a Mormon missionary from the United States, who disarms one man and pummels another with punches. In the end, the apparent attackers flee on foot, leaving behind their motorcycle. “The missionary feared for his life and reacted,” Eric Hawkins, spokesman for the Church of Jesus Christ of Latter-day Saints, headquartered in Salt Lake City, told The Washington Post late Wednesday. No police report was filed, he said.
