Excellent thought but same time heartening also. Children with violent/extremist mind-set will be required to re-evolved in to humanity stream with may be under several psychological / medical help. But the rehabilitation will be a challenge in terms engaging them and preventing them from the resurfacing in to earlier life style and practices. It will be like performing surgery on DNA system. It is pathetic that the entire generation is already spoiled but the endeavour to bring them back to main stream shall be challenging too. Wish the blessings of almighty.
