An understandable sentiment.
I’d rather they suffered the misery of the weight of their deeds, and then made their peace with God.
Me, too. In fact, the Japanese leader of the Pearl Harbor attack later converted to Christianity due to a former American POW and Doolittle Raider, Jacob Daniel DeShazer. I found out about him through a tribute to him on television. Forgiveness was his inspiration and no one who reads about his own change of heart during his captivity can say he didn't practice what he preached.
It serves no one but the Devil to nurture hate and anger, as hard as it is to not feel both when learning of such cruelty.
I don’t think the japanese beleive in god.
