First off Jews must do this to qurananimals sometimes you have to get down in the dirt with eternal enemies.This is something i hope every leftist Jew and his or her family members who agree with said leftist will experience
I do not agree with your position. It stands against many Jewish principles to torture and maim our enemies. They should only be killed quickly and buried...
I take this from the lesson of the Torah mitzvah concerning the 'hanged man'... A hanged man should not be left on the gallows over night, he must be removed and buried. Judaism places a great emphasis on respecting the human body (both Jewish, non-Jewish, and enemy)...
Obviously those who engaged in this terrible desecration of Hashem deserve death.

The courts administer four death penalties: stoning, burning, beheading, and strangling. The first three are explicitly specified in the Torah for various sins, and the punishment for murder too is beheading. It is a tradition received from Moses that whenever the Torah does not specify the manner of execution strangling is meant. The courts are commanded to administer these penalties to those who deserve them; and there is a special prohibition against not executing a convicted sorcerer, as it says "You shall not let a sorceress live".8 We are commanded to hang a male idolator or blasphemer after he is executed, but it is forbidden to leave him hanging overnight, as it says "And if there is in a man a sin for which he is sentenced to death you shall hang him on a tree; his carcass shall not stay overnight on the tree... for the cursing of G-d [he] is hung",9 and it says "[And a person that acts highhandedly...] blasphemes Ha-Shem".10 We are commanded to bury executed persons on the day of their execution, as it says "For you shall bury him on that day".9,d
