Yeap!
Some people just physically can not (or will not) see how genuinely sick they are. Just imagine that they might have a partner and kids and may seem like the most normal person to talk to, yet mentally they are so broken that they love seeing these videos just to get some gratification and then feel that the behaviour is so normal that it's OK to boast about it behind the anonymity of being online.
I mean just as a litmus test - in their post simply replace the words Orcs with Jews, Blacks, Women, Gays or any other word and see how the reaction to their would be different. Yet just because a single person in charge has made a decision that ends up with some random 19yo from Moscow getting drafted into the Army and end up in the Ukraine, it makes the poster believe that their post is perfectly OK and they know that others will happily cheer them on.
I bet they would say that they are a "good person" or a "moral person who believes in right/wrong" too if asked.
