At the end of the day, this is fiction(as Junoonian very rightly reminded us in her post) Just the same way feeling like u have no choice but to threaten to burn someone's family and force them to marry you, you also will have the an alternative to marrying a married man.
But this wouldn't make for a compelling story would it? This is a story about extremes.
Most of us are pretty lucky to never have to deal with extreme circumstances. But what would you do if you did? What would you really really do? I'm a vegetarian and I am reminded of as a kid, at school, I used to get asked alot, 'if you were stuck on an island and the only food available were animals, what would you do'...of course I used to say that this is an absurd question as on an island I would probably have fruit available and the likelihood of me ever getting stuck was slim, but my friends would push and say come on, imagine if you were in that situation, what would you do??? And I always used to say, die of course!! I would never ever eat meat!! π , now many years later...if I think of this question, my actual answer is, in such an extreme situation, as a normal human being with the fundamental urge to survive, I probably would eat whatever was available...
But this thought process comes with maturity, pragmatism, bring realistic. My point on unbending principles, is that it is good to have the moral high ground, and indeed admirable. We all should be like this. But sometimes life's circumstances are such that you may have to be flexible if it's a matter of survival.
If you think about the classic movie 'Deewar', it shows this as well. Amitabhs character is all grey. Did he really have to turn to stealing? His brother and mother certainly didn't think so, but in his mind he was justified and couldn't understanc why they didn't see it. He then goes to God and chides h for putting him in this extreme circumstance which made him take extreme decisions. Whichever point of view you agree with, the film makes for compelling viewing. It's a story about someone who made certain decisions (right or wrong)
And we have the same here.
