Should you 11 year old boy be allowed to play saints row 2

Saints Row 2 Is rated M for Mature, which means that you should have to be at least 17 Years old to play the game.
I THINK THAT SAINTS ROW 2 IS NOT THAT BAD OF A GAME NOT HALF AS BAD AS GRAND THEFT AUTO BUT SAINTS ROW TO IS LIKE GRAND THEFT AUTO BUT FOR KIDS AGES 10-15
SO IF YOUR KID IS SAY WELL 10-15 THEY SHOULD DEFIANTLY BE ABLE TO GET THIS GAME EVEN THOUGH IT IS RATED M-MUTURE.
