Why do humans do these things? If we remove the why then we remove the harm inflicted on others. I'm saying that the nail doesn't have to be hammered, but you think that it does. Do you think that people HAVE to inflict harm on others? I don't. I know that pain and suffering will always exist, but I insist that it can be lessened if we work at it.
Regarding religion, if they don't find a reason to kill others, then they won't. You act like people are animals waiting to pounce on other unsuspecting people to kill them. I, personally, am not looking for reasons to kill the person just to the right of me. I simply have no desire to harm this man. But according to you, I'm ready to pounce. But if you plant the idea in my head that this man is seconds away from whipping out a pistol and gunning me down, then that IDEA might change my actions.
Humans are animals. We have cognitive abilities, but that only separates us from the animal kingdom by one factor. We have the same lower-brain functions as animals, we just layer reason on top of those functions. Unfortunately, the ability to reason has not shown the ability to overcome those basic animal behaviors in all humans. Until that evolutionary step occurs, if it ever does, humans will still harm humans every single day.
The nail doesn't
have to be hammered, but the nail
will be hammered, because humans feel the need to hammer. Again, this is based on observed human behavior since the dawn of recorded history. Paleontologists have found numerous examples of humans who have died at the hands of other humans before any of the world's current major religions were ever founded. There is no evidence to suggest that humans ever have lived in any kind of utopian peace with each other, and being animals such a concept runs counter to observed behaviors.
Animals, including humans, compete for food, shelter, prosperity, safety, comfort... you name it. The basic things that all animals want, humans want, just in human ways. We use a variety of reasons to do this, with religion being just one of tens of thousands.
I am not telling you what I
want to happen. I am simply telling you what is easily observed to happen, and which has happened since before humans were truly
homo sapiens sapiens.
I agree that if they don't find a reason to harm others then humans won't, but those reasons to harm are as multitudinous as grains of sand on the beach. You're stepping into a weapons store with 10,000,000 weapons and saying, "If we take away
that gun, less people will be harmed." I'm saying that the difference between 10,000,000 excuses to harm people and 9,999,999 reasons to harm people are statistically zero.
