Why do people make such a big deal over killing?

Killing if antithetical to the purpose of existence, propagation. The moral outrage most people feel at unjustified death is an evolutionary trait tied to the instinct of self preservation.

It is not all of society that finds killing wrong, or death as scary. It is ours that does, we discourage killing because it is one free person taking another free person's life. Its a philosophical interpretive thing, which means the good and bad side are all a perception. Those people who post their comments online like "oh my goodness! I cant believe someone would do that!" Do not really care, because if they did they would dedicate their entire lives to the cause. We are a living thing, which means we must kill to survive, but being as "civilized" as we are we no longer have to hunt for our food. That weakens us to such a degree that we feel our hands are clean, when in my own perceptive reality, makes us much dirtier. We just pay someone to do it for us, and then buy whats left at the store and eat it. Those animals are horrendously tortured and some of us do live their whole lives in an attempt to stop such things. Even vegetarians take life to breed their own, given the knowledge that plants are a living energy. There is no way around it. Murder on the other hand is purely circumstantial and perceptive to the individual because there is a good and a bad side to each one, you just have to dig deep down to find both. Our society won't last this way, and that is a fact, but we will learn the hard way just how soft we have gotten, and more murders will ensue. But, would it be a good thing for it all to come crashing down? Thats up to you and what you do about it.

I have no dam clue why, and have always wondered the same thing, only far more harshly I might add. Everyone has the instinct inside them, EVERYONE. Most refuse to admit it, however, becasue sociaetys norms and laws tell them to deny their nature. Humans are warlike, murderous, jealous revengeful creatures by nature. I want to kill at least two people at any given time of the day and night. The ONLY reason said peoplea re still alive today, is becasue of police, laws and the risk of trouble. I will not kill while it is illegal. the SECOND it became okay to do so, there would be a lot of folks needing to watch the heck OUT fast.That is my nature, it is everyone's nature. Murder is as old as time.It is laws that have changed. Not humanity. I have always suspected that if the end of times arrived, and the world became like a Mad MAx movie all in all, I would survive like no one would expect, becasue I could blow someone away for threatening my safety, in like a second, and walk away and not care. And thats the offensive truth about me. I am certain someone will call me a psychopath, or some crap now below this comment. Oh well. Call me names, when the world ends, or the laws change back to nature, Ill be looking for you next ok?

No, it's nothing new. But neither is stealing. So your thesis doesn't make any sense: what you are basically saying is "it's OK, because people have been doing it for a long time".

ps Maybe if someone kills YOU (not by accident) you won't say "meh", but will probably pee your pants and beg for mercy.

Because it's God calling not mans only God can decide who lives and who dies. Plus at the rate we going man is going to be extinct because we like to kill.

Never heard of him until you mention him and God do exist. That's what's wrong with the world now and that's why we are our own enemy and will bring on our own demise.
