Touching moment killer about to be hanged is spared execution by his victim's parents

This is just so touching and shows the power of forgiveness in it's purest form...An Iranian, Balal, was sentenced to death for stabbing 18-year-old Abdollah Hosseinzadeh Jnr, during a street fight seven years ago. He was finally taken to the gallows to be hanged today and as they were getting for the victims parents to  to kick him off the chair(which is the tradition), the victims mother instead gave him a dirty slap and choose to forgive him, to the shock of spectators .She & her husband then removed the noose off the murderer's neck . See the pictures below

 The killer's mother who didn't expect it was over-joyed then ran to hug her ....The victim's father, Abdolghani Hosseinzadeh, revealed his wife had a change of heart after her dead son appeared to her in a dream. He said:

  'Three days ago, my wife saw my elder son in a dream telling her that they are in a good place and for her not to retaliate.This calmed my wife and we decided to think more until the day of the execution. Do you think she did the right thing?
