You have made some good points here, but those who masterminded this tragedy are there flexing with their family, all we need to do is pray and orientate those tools used in destroying humanity to think, as their kids will also suffer in the future. Also, they should ask themselves "why do we need to kill" if they are able to give a tangible answer to this question them they have got to be in the psychiatric hospital, but if they think that there is no reasonable excuse for killing people of the same flesh and blood, then they are worth to be called humans.
