I've managed to not watch any horrible footage or traumatic picture of that massacre, of that pogrom. I am horrified by the morbid curiosity of people in social media. I've read stuff and it was already traumatic to just read them, I didn't allow my mind to picture them.
That said, one of the purposes of showing those images might be to prepare people for the unthinkable. Dehumanization is a defense mechanism that allow normal people to do inhuman things. When a person or a group of humans become nothing but objects, not human anymore, then even the most basic empathy ceases to exist and massacre of that kind or even mass murders with any weapon available become "tolerable" if covered and justified by a simple concept namely
the right to defend oneself.
I've already heard the words of dehumanization from the terrorists and now mere people start to use the same terminology. If people consider "Hamas" and "Palestinians" as synonymous then surely the Talion law can apply its "blind justice". Although I'm sure most people who watch this horrible events never heard of
Al-Qassam Brigades and don't distinguish between the political factions and opinions among the Gazans. I heard people saying that the hostages are considered as already dead by some Israeli officials... What is about to be done to Gaza is unthinkable.
The world configuration and geopolitical status has never been so auspicious to WW3. I've already heard people using eschatological terms from every side. When you already have a script albeit written thousands of years ago, all you have to do is direct the movie. The actors are ready, they stand by for the director to scream "Action !".
