Well, now we know that the brother is a violent psychopath. Daddy dearest probably has to constantly clean up all of his messes, considering we know how violent and unstable he is (slapping his step sister, beating and nearly killing his stepmother, apparantly raping 3 girls (as said from an article we saw on the computer in an earlier chapter) and from what i can tell going after Eunha's sister....still doesn't explain anything. I really wish we could get some more clues.
