This was intense and gruesome and I loved it. Very easy to hate some characters and love others, even if all of them have their reasons for their (mostly bad) decisions. The art is great and the ending is superbly disturbing. Loved the song in the last two episodes as well! 
I do tend to rate webcomics slightly differently than books-- If this was a novel without illustration it wouldn't be that high. But I enjoy webtoons a lot and have a ton of respect for the creators of webcomics in general knowing how much work it is.
