Be ready always to give an answer to every man that asketh you a reason of the hope that is in you. 1 Peter 3:15
Trivia: According to 1 Peter 3, who preached to the spirits in prison?
Here is a plot of the number of cruel passages in each book of the Bible.
Leviticus, Jeremiah, and Deuteronomy are in the lead here, with 141, 106, and 93, respectively.
But since the books of the Bible vary greatly in length (from 2,527 verses in the Psalms to only 13 verses in 2 John), we might want to adjust our metric accordingly. The following graph does this by plotting the number of cruelties per 100 verses in each book.
When this is done, Amos and Leviticus are highest, with 16.4 and 16.3 cruel things per 100 verses, respectively.
Another way of looking at in the Bible is to plot the number of in each book verses the number of verses in the book.
Such a graph is shown below.
