One of the major setbacks in sending humans to mars (In my opinion) is still the unknown effects of radiation in space. Who ever goes first will be the first. There is no way to simulate what it would be like because no one has ever done it. We can guess and speculate, but that’s all it really is.
So, if we can’t know until we try it, why not just try it?
Find a volunteer crew and send them on a slingshot trip around mars and back to earth. Upon their return, monitor their progress and basic health and then we can start to draw real conclusions with actual data.
If we send 4 people in good health from various backgrounds we could derived some useful data. Supply them with a pension of $100,000 a year for twenty years, at a cost of 8 million, that’s a very good deal for data like this.
I know people are going to bring up the “ethical issue”. Yes, we might be condemning people to death. But it’s volunteer, they will be compensated and I don’t see any other way of getting helpful data before we try the real thing.

Radiation is not a serious problem. A lot is known about the radiation environment between Earth and Mars, it's possible by using the on board supplies, such as water, to provide sufficient shielding. BTW there is no spacecraft capable of sending even one person to Mars and back right now.

Why not? I’m going to be blissfully optimistic and general here, but if we can put a robot on the planet, why not a human around it? While obviously nothing is built at the moment, using current technology, it is very feasible.
I’m putting my hopes in the private sector.

Robots don't need air, water or food. There's no human rated spacecraft large enough to hold the supplies for the trip and even if there were, there's no launcher capable of sending so much mass onto the trajectory. Sure, both of these could be developed, they would cost many billions and take many years.
Better to build the right spacecraft for the job of sending a crew and landing on Mars. That's what NASA is planning to do and has already started with Orion and Ares I. They will be part of the Mars architecture together with the big Ares V launcher that will be based on Ares I.
