It is a tough pill to swallow and dissapointing when it turns out that people we idolize and look up to aren't the people we hoped them to be.
In any given population of people there is going to be a wide range of people from really horrible to really great (and everything in betwen). Being a hockey player, actor, or any kind of celebrity doesn't automatically make you a great person. It just makes you great at some things that happen to make you famous.
At the end of the day, take care of yourself, be careful of who you idolize and make sure the people you choose to emulate are deserving, and represent the kind of person you want to be.
