Let's go to Mars - but why come back?

Since so much time and money is spent into getting people BACK to earth,
aren't there people who would volunteer to never come back? There are so
many of us on the planet, and I'm sure there would be people who would be
willing to go through the training etc and know that they'll never return.

I'd go if there was a chance I could see Mars with my own eyes and maybe
even land on it. Better then being wiped out in a car accident.

What do you think?
