Eva, you said that "mom dragged him there." You are being overly aggressive toward this mother.
I would suggest you people wait until the entire story comes out before casting judgement on this child and his parents.
What I am reading on this thread is unbelievable. It sickens me that some insist on blaming the child.
There by the grace of God there go I. We really do not know how we would react if under the same or even the most horrible unimaginable circumstances.
Those of you who are "just trying to understand", there is no understanding of it until the facts are out.
Instead of spending your time in judgement, try spending time praying for these people.
Again, you are projecting. The film that I saw showed the mother leading the boy by the hand. The kid looked very unhappy and uncomfortable.
