IDK. You'd expect somebody would test his newly found strength in a more controlled environment, when facing of an enemy with it for the first time. Somethingalong the line of a single enemy and surrounded by his own allies and not the other way around + a possible hostage against him. If this isn't a world with HP-drain instead of injuries, one lucky hit is all those punks need to take him down. Taking risks is the fast way to major successes, but avoiding unnecessary risks is the way to live a long life.
