Thanks for posting this debate. I will do my best to convince the audience of the con positiion. merriam-webster defines cruel as "disposed to inflict pain or suffering : devoid of humane feelings". i would ask pro to consider this definition of cruel going forward with this debate.
my opponent forfeited every round so im guessing he wanted to use a strictly utilitarian definition of cruel as Mengele killed more people. Dahmer was just as cruel if not more cruel to the consciousnesses that he did kill. Dahmer was a registered sex offender and brutalized people worse than Mengele did.
