My Prayers To The Victims of the Movie Theater Shooting

Hello fellow readers. I normally don't do posts that aren't book related, but due to the recent events of the Colorado movie theater shooting, I wanted to dedicate a post to those victimized in their wrongful deaths and injuries.
This subject is actually very personal to me and hits a sore spot, as my sister and her boyfriend live in that particular area. They were actually planning on going to that very same movie theater for that same movie, and thankfully decided to stay home. I even went to that same movie theater awhile back in December when I was visiting my sister for her Master's Degree graduation.
Through these awful deaths, and the horribly mass injuries, it makes me think, that even though this is a major cliche, we should in fact live every moment in life to the fullest, because you never really know what could happen.
It also makes me think, "What if?" I don't mean to be selfish, but what if my sister and her boyfriend had gone that very night? Would they have experienced the same awful fate as many of those victimized had? It also makes me think "what if?" What if there was a way this could have been prevented? Like from some fellow tweeters on Twitter that had stated that, buying mass bullets and obtaining at least four fire arms, shouldn't have rang a bell to someone in the area?
It also makes me think why. Why were those people killed and injured when the killer is still alive?
This horrible event also makes me think what was going on in that guy's mind when this was happening. Why choose that very same spot? Why choose those people and that movie? The news also claims that he was on the verge of dropping out of getting his P.H.D. in neuroscience. Something had obviously snapped inside of him to make him do this. Was he on drugs? This situation was obviously planned way ahead of time, and premeditated. Some might even think that this was a suicide attempt, as he had to have known that if he didn't kill himself in the end, he'd probably get life in prison or the death penalty when caught. But it still didn't explain why all these innocent people had to suffer for his benefit. I've been rambling on for awhile now, but I wanted to extend my deepest regrets and condolences to those who were wrongfully killed and injured from the psycho path.
