Revenge gets you glory in Russia

In 2002, Vitaly Kaloyev’s wife and children were killed in a plane crash. He stalked the air traffic controller who was on duty all the way in Switzerland, knocked on the man’s front door, and stabbed him to death...after serving just 5 years of a prison sentence, Vitaly goes back to Russia and is welcomed there as a hero...

Well, not by all, but enough for the story to make it out.
