Its called necroviolence. Like the systematic destruction of cemeteries, attacking the funerals... For the families, it prevents them to mourn their loved ones. Desecrating the bodies is the same thing, with dehumanization on top of it.

You don't need to be religious to find that awful :

"Today on our show: we will fuck their mothers. We will take out your eye a little. We will take out your other eye [pokes both eyes out]. You son of a thousand whore. You deserve it"

(NSFW)

In one clip, a man is seen urinating on dead bodies, presumably of Palestinian fighters, that have been stripped, scorched and splayed on the ground, either before or after their deaths. “This is what we are going to do to the Arabs,” one witness is heard commenting in Hebrew. In another clip, an Israeli in civilian clothing can be seen repeatedly stabbing the corpse of a Palestinian fighter in combat fatigues.

“Hole him a little,” another Israeli is heard saying. “Won’t we give it to you in the stomach? And rip? Won’t we take out all his fat?” In a third particularly gruesome video, an Israeli man uses the rod of a squeegee to repeatedly beat the face of a dead fighter, and then to poke each of his eyes out.

The videos are replete with foul language and calls for sexual violence. “Today on our show, we will fuck their mothers,” one Israeli says.

The Geneva Convention of 1949, to which Israel is a signatory, characterizes abuse towards captured enemy troops, and the defilement of their dead bodies, as war crimes.

In other videos uploaded to the “Terrorists from another angle” Telegram channel, Israelis are seen driving civilian vehicles back and forth over the lifeless bodies of men presumed to be Palestinian fighters, stripped down to their underwear.

“Amit, this is for you sweetie,” an Israeli is heard saying in one of the videos. In another clip where a presumed Palestinian fighter is slowly smeared into the gravel road, Israeli men can be heard laughing loudly, while one of them narrates the nauseating scene: “Very good, Gershon! In the ass! Half a corpse! In the ass!”

After the Israeli army declared war on Gaza, the Telegram channel has continued to fill up with images and videos of charred Palestinian bodies of a different kind: the civilian victims of Israel’s intense aerial bombardment of the Gaza Strip – men and women, young and old – still termed “terrorists” by Israeli officials.

Horrifying clips of Palestinians picking their mangled, mutilated and murdered family members and friends out of the rubble are regularly uploaded to the channel, accompanied by expressions of joy.
