I can think of a few people I'd like to put on that first flight!
I cannot fathom why anyone would want to do this. First, you'd lose years of your life getting to Mars. Just picture what that one part of this would be like. I'd go nuts from the isolation, the distance from Earth, the reality that everyone I know is forever out of reach, etc. Then the desolation once on Mars, combined with the continuing realization that your old life is irrevocably gone.
Just doesn't sound too appealing to me.
