am not sure why you aer getting so aggressive.. you said earlier if it was your children who had been hurt you would murder the perpertrators.. you are clearly coming at this from a much more punitive stance.
i don;t know what the answers are
i don;t know the history of the perpertrators, but i would be willing to bet that they have not had a nice ,normal, safe upbringing, with rules, boundaries, lvoe, compassion and care. i would bet there is abuse somewhere along the line, be it mental, physical, emotional or sexual or a combination. i would bet there is little or very interrupted schooling. i would bet there were few if any postive role models in their lives
i don;t think the answer is locking them up in solitary nor do i think it is allowing them to play on a playstation all day.
the answer is not just what happens to these two boys, but to the children like them, they need to be helped before another terrible act like this ahppens.
as i have said before, abuse is a reason, not an excuse. but you really have to ask how children of this age can act like this. what factors have led them to this, taht at a young age , tehy feel their own lives and those of otehrs are wortheless?
none of that points to a normal start in life
