Thanks. A lot of the comments are well worth reading through and especially the ones from the friend as I do think it gives a good perspective on this tragedy.

I think the sheltering and isolation that the children had to live with went too far to the extreme.
Whether someone is homeschooled or not , it is important IMO that children are allowed to mingle with their peers at least some of the time during developmental years. It serves some important functions in child development.
I know some parents who are homeschooling their kids and they have social events to make sure their kids get that exposure which I felt is great for them.
Being able to succeed and fail with various competitions with peers is one of those things that I feel is important. Whether it be extra curricular activities like sports OR work OR classroom competitions like tests where kids always ask each other how they did on tests OR simple unrelated competitions like "Lets see who can run to the end of the street Faster".
All of those types of peer competitions and just silly and fun stuff with peers helps children learn valuable lessons. Lessons that cannot really be learned elsewhere.
I think when there is too much isolation then the children are left to wonder in their own minds about all sorts of things and they have nobody to run their thoughts by. Because they will not discuss certain things with parents. No checks and balances for them. Nobody there to tell them...."No Silly, That is just crazy".
Their thoughts, minds, and development can go in very twisted ways and with nobody around them to ever help change their thinking and correct their mistakes they can convince themselves of horrible misdirections.
Because let us remember an important point. There are lots of things a child will never talk to their parents or teacher about. There are many important subjects that a child will never dare talk to their parents or teacher about but they will comfortably share those kinds of things with a peer.
Anwyay, I am not trying to put the blame solely on the parents because there could have been some valid mental disorders, however, IMO I do think the style the parents had of sheltering their children to the extreme could have contributed to this tragedy.
So sad.
