To answer the first question, the situation could go both ways.  No the guy shouldn’t steal from the Doctor, the Doctor has the right to profit from his discovery.  But at the same time, the Doctor could have a little compassion and let the guy set up a payment plan or something.  His wife was dying of course he would do what he could to save her.

Ok, so after reading the article, I think I answered closer to the little girls answer. But at the same time, I think that my logic is closer to that of the boy’s.  I said the man should not steal, but the logical thing for the Doctor to do would be to sell the drug on a payment plan.  He could charge interest and make more money. The Doctor needs to look at the situation as a profitable experience, instead of just letting the woman die.
