Of course this analysis does not consider the extent of the cruelty in the marked passages.
And that is an important consideration. Is Numbers 31:14-18, for example, more cruel than Quran 5:33? That is something that each person must decide.
A good argument could be made that either book is the most violent and cruel book ever written. The
award would go to one or the other, for neither has any close competitors. It is frightening
to think that more than half of the world's population believes in one or the other.
*The actual percentages are probably somewhat higher, since not all cruel or violent passages are marked in
the SAB/Q and many of the marked passages contain more than a single verse.
