Human lives aren't valued by our higher ups, I can't help but feel that. These things could have been cut from the root, so many of these incidents could have easily been avoided. And these ISIS fucks and those random terrorist groups don't appear on their own, cut the funding, cut off the countries that fund them, simple as that.
Every civilian, wishes for peace and prosperity, it's ridicule to believe that the masses want blood, however the masses are tools, and so is religion. We know that states like Qatar, Saudi Arabia and Kuwait, but what does the western world do? Negotiate oil prices with these lunatics, let them host your world cups, get them to pump money into your economy by buying football clubs.
This needs to be cut at the roots.
As for this specific case however, it can very well have been done by a random person, heck somebody ran up in the Canadian Parliment with a rifle and killed a man before getting himself killed, was a recent convert apparently. Regardless, I hope the families of those who got affected directly by this incident get to bury their loved ones and mourn their lost without having a distasteful opinion of all muslims, hate doesn't eliminate hate.
