News Update: //The parents "apologised". Killer committed suicide. //
The news about the killer are right at the beginning. Jump to 5:50 to see the update on the family situation. It still has some of the footage that might upset you. - If you want to see two random awesome people, go to 2:49.
This is still very disturbing.
Nature or nurture?
In this case i believe that this family is creating a monster. Innocense stolen and filmed. His attornies will have plenty of evidence if he commits a heinous crime.
They should not only lose the children, but be imprisoned for abuse.
More update:
They(the parents) made another video. There some allegations from an ex-wife. The parents are blaming the commentator for receiving death treats and such.
Warning: some footage in the video might upset you.

Update 3:
