just a bunch of russian black metal edgelords who satirized the orthodox church and religion
if you know the back story then it becomes more of a cringe strory.
Seriously, the only thing scary about this if you don't know the backstory because you might think that this is some ambigious shit, but in reality it's just some bad satire music video. Kinda similar to that android. The creator wanted it to be a funny singing robot but ended up being a internet creepy meme.
