Should we still pray for Osama Bin Laden?

Although Osama Bin Laden was the spark that ignited a war, and killed thousands of innocents, is it still our duty to pray for him? He was a human none the less, and still created in God’s image and holiness…with our prayers, he may be saved from the worst of Hell…should we show Compassion, or Vengeance…What do you think? Pray or Don’t pray?Please, don’t be rude, I just want to know your opinions. Thanks
