I sympathise with the twins. However, I somewhat agree with NFS4. As someone (Conjur?) else said, not too many people choose the concept of "freedom" [as we grasp it] over existence. And rightfully, the meaning of "normal" was questioned. I'm not sure we'll all agree about the definition or attribute. Nevertheless, I think we can be certain about something: Life experiences of most people whom we think are in die suffering is not as measurable as we think. We use our personal experiences, which in our case tends to be a much better life experience, consisting of luxury, to measure up that of someone else in another part of the world and with a different background. The truth is, if you grow up in suffering and are surrounded by people just like you, you will eventually adjust--particularly for as long as you can get bread to eat at the end of the day. The people who are usually willing to give up life for freedom are the revolutionists and non-conformists. They aren't very many.
It's possible that in spite of the warning they got of a 50/50 chance they took things for granted with the publicity and the famous, top doctors who would operate on them. Perhaps they measured their chances as having increased therefore. On the other hand, what may have made life much difficult for the twins and made them willing to make the sacrifices was the type of society they were in and knew. I couldn't imagine them not experiencing teases, harassment, exclusions, etc. If they lived in a different type of society, such as the USA, just maybe they would have come to accept what they had and decided it wasn't worth the risk. It reminds me of the twins Katie and I forget the other's name in the USA . . . they were conjoined on the head too. As far as I know they are still active and enjoying life. Yes they go through inconveniences, but it isn't like it disturbs them everyday. And they both had different career plans. Then there were those two brothers that Jerry Springer had as regular guests (of course this was before Jerry lost it completely with his staged fights. LOL). I forget where the conjoining occurred.
P.S.: How's the government paying such huge sum? :Q Is it coming from personal pockets of the officials or what? Or does the Iranian government offer free healthcare (i.e., a socialist system)?
