This is the title of a current post on r/RussiaUkraineWar2022 (160k subscribers) that is 95% upvoted. I'm not going to link it for obvious reasons. And yes, the comments are even worse than you could even imagine.
These people have chosen barbarism.
This is incredibly disturbing and similar content has been all over reddit for months. I've even seen comments from Redditors claiming that they spend hours a day watching the goriest videos they can find of Russian soldiers being tortured and killed and then gloat about it afterwards, not only is this horrifying for obvious reasons, it's probably fucking a lot of them up psychologically a lot more than they realise.
17th century diarist, naval administrator and drunken sex pervert Samuel Pepys would regularly watch the violent public executions of parliamentarian regicides from the English Civil War and basically gave himself PTSD from witnessing so much torture and death, despite his loathing of the people being killed.
TL;DR: Don't watch torture and ultra violence for fun you giant weirdos (this is aimed at those subreddits, not you OP)
This is nothing new, unfortunately. It was channers watching ISIS beheadings on liveleak a decade ago, and I'm sure there was stuff before that.
I think a little bit of combat footage can be okay (not good for your brain, but instructive) for those who might anticipate defending themselves at some point to see, but who are these people preparing themselves to fight by doing this, the Russian Federation? Lol
