What would an Arahant experience, as a slave in a labor camp? I like to put things in perspective by using extremes to create high contrast.

Let's imagine a person who has become an enlightened being, let's use the word "arahant". But imagine that they're put in an inescapable, hostile, deadly environment: a slave labor camp.

What would this arahant experience, and how would it achieve those experiences? What would be this arahant's view on reality (reality as in the combination of objective and subjective reality)?

From what I understand: if you master your mind, than you no longer suffer mentally; you might feel pain, sadness, grief or whatever, but you no longer suffer from the experience. 

But imagine that this arahant has a child, or a wife, who are taken away to be killed, never to be seen again.

The reason I am asking this is that I just can't imagine that a person wouldn't fill up with hate and anger, disbelieve in any cause and become completely hopeless. How would an arahant hold itself in such a horrible situation? I can't imagine that it is even remotely possible to focus oneself on the teachings of the Buddha. Bad food, bad sleep, laborious days, bad shelter, bad clothing, bad physical health, etc... I couldn't even focus on where to put my next step! Let alone, keeping up righteous mental activity.

EDIT:
For those who are interested, I summarize what I learned from asking this question. I was lost in thought with some imaginary situation (described in this question). Like trying to prepare myself for any situation that might every arise and compare my current state with a state that would be required and trying to get there. For that part I was no longer present with my actual experience. Instead I created a whole lot of (now I see) unnecessary experience from which I mentally suffered. The answer I accepted is the answer that first answered the question on the matter asked, and then guided my attention back to my self. I experience the answer as: first addressed the wandering mind and get its attention, then give an answer that the mind can chew on. Then provide the answer with the 'real' value. That made the chewing of my mind on the subject decrease immediately. I feel more tuned in to the moment of now after reading it. I feel thankful.
First of all, Arahanths never feel sadness, grief, hate etc. They  don't have wives, but they may have ex-wives.

if the Arahath has psychic powers he might fly away to spare the people from acquiring extremely bad karma or he might stay if he saw it as an unavoidable consequence of a past Karma.

Either way, he will never get upset no matter what happens. He would try to make the people come to their senses, if he sees potential in them to be better humans. Otherwise he'd remain in a meditative state when not attending to the maintenance of the body.
