Weird news - An eye for an eye - Iranian man to be blinded for throwing acid in girl's face

This is a moral dilemma for many people. What do you consider the just punishment for a man who stalked and pursued after a girl, and when she said No, was angry enough that he decided to punish her for this refusal by throwing acid in her face. Now, getting acid on the face is a grievous and horrible fate, since the acid causes immense pain by burning the skin, and in her case, went into the eyes, blinding her. The acid also dissolves some of the structures of the skin, causing the face to become disfigured, and a huge number of victims of acid attacks never fully recover even after a number of plastic surgeries.
This happened in Iran, where there was a twist. The judicial system is based on the Sharia, which allows the victim to claim the same punishment on the accused as he has done, and the victim demanded this revenge. She refused to accept blood money, and pushed for reciprocal punishment, and the judicial system of Iran is delivering, where the accused is due to get 5 drops of Sulphuric acid in each eye, which will cause blindness. Causing blindness did not cause as much pain as the prospect of being blinded, and the accused is very repentant. However, this is also seen as a form of punishment that is barbaric, and is being opposed by many other countries who have filed protests (link to article):

A human rights group on Saturday urged Iranian authorities not to put acid in the eyes of a man found guilty of blinding a woman who scorned him. Majid Movahedi is scheduled to be blinded by having five drops of acid in each eye Saturday, according to Amnesty International.
Movahedi was convicted in 2008 of throwing a bucket of acid on Ameneh Bahrami.
The attack blinded Bahrami, who sought to have authorities render the ancient punishment of "an eye for an eye" in accordance with Islamic law. The rights group is urging Iran to forgo the acid punishment. "It is unbelievable that the Iranian authorities would consider implementing such a punishment," said Hassiba Hadj Sahraoui, an Amnesty International deputy director.
