Normal people don't post 'memes' with images of dying people in them. If you don't understand this imagine a 'meme' that showed that terrifying image of the dying Iryna Zarutska in it, murderer right behind her, and posted some edgelord caption below it. You only do this sort of stuff if you're completely screwed in the head, generally caused by political extremism.
Click on the section in the article that links to his 'memes'. I'm not going to directly link to it because I find it disgusting. There are 3 provided in the link including one with an image of Charlie Kirk just after he had been shot in the neck and an edgelord comment surrounding it.
