The sad truth is that in reality bad people exist everywhere, and no matter what you believe (chance, god/devil, or simply bad/ill intent) everything happens for a reason. I don't think anyone aside from humanity can be blamed for these instances. People like him would seek to blame others for his choice, but that's just it... there's always a choice.... and he made the choice to take innocent lives, and record it as a live stream. It's disgusting, upsetting, and truly an embarrassment to humanity as a whole.
You never know when any day could be your last. That is why I always tell my fiance I never went us to go to sleep upset with one another, I never want us to leave the house with any regrets lingering, because you just never know what's going to happen. Anyway I digress. I wish you all nothing but 100% safety in your journey through life, both online, and offline. Be alert, and be careful.
