I'm not in a position to make an assessment as to whether the individual residents of the camp have in fact renounced violence or not. Certainly, I too was appalled in watching that video; it was a very distressing situation to see unfold. It will be up to the UNHCR and then the authorities of each receiving country to determine on a case-by-case basis the situation with respect to each individual in the camp.
