Yes of course Yes! Athletes should be role models, whether they want to, or not. A lot of children and young people want to become a top athlete, so those who are so lucky and so talented to be a top athlete has got to be a good role model for all of those who wants to be like them. There is a lot of athletes who are good role models, and shows the young people who look up to them how you should act when you are a top athlete. They show fairplay, how to be healthy, and that you've got to work hard to achieve your dreams.
But there is also the athletes who isn't good role models, and the young people has to ignore the stupid things they are doing, and start admiring the ones who act good and exemplary. The kids needs a big star to look up to, otherwise they´ll not strive to be the best.
