You might be aware that Asia Bibi, a Pakistani Christian formerly condemned of blasphemy and recently liberated, is being persecuted by some (what sometimes the Western press calls "radical" or "extremist") Muslims in order to put her to death with their own hands, given that the government "refused" to do so.
Now, in my google search, I find there is plenty of writing in the Quran about forgiveness (not minding that her culpability has not even been proven). A good example is here. Importantly, this mercy seems to be deserved also by non-Muslims. So, I don't really understand why these readings are not taken into account by those who persecute Asia Bibi. Are these verses perhaps superseded by other verses indicating that for some crimes, mercy is not longer to be offered?
