Moreover, I could have said about other Historical Figures who was much more evil in history which even in their bias it is so much clear that they have been a bit more softer. Even in the story of Chingiz-Khan or Ugaday-Khan. Or even some Crusader have been written in a good manner in some point of history by islamic scholars. However, giving such points to the one who was 100% muslim and united the more than half of the asia under one ruler is evil.
