Feynman is one of the best role models for a 14 year old. Maybe you object to some of his life choices but as far as I'm concerned the world would be a much better place with 'more Feynman' in it. It's all relative, look at the various alternative role models available.
It may help him open his eyes more and appreciate ways of living that don't fall in line with the common American view. You can be a great genius and still a weirdo!
