Why have people throughout history sacrificed children?

Due to recent news on the elitist rings of child pedophilia related to "satanic" rituals and sacrifices, I started investigating the origins of these practices and which systems of rituals are the most used today.

In Western civilizations, including the USA, I found it appears the most used system is based on the Kabbalah where the original teachings have been perverted. An example is the system practiced and preached by Aleister Crowley. This system seems to be the one predominantly followed by Hollywood and the entertainment media types and those affiliated with them. The pyramids, one eye, tree of life and similar easily recognizable symbols used throughout their industry is one clue to their chosen system.

The level of perversion of the original teachings of the Kabbalah is reflected in whether the abuse of children is incorporated by the group participating. In the same way, no two Christian denominations are exactly alike, and sometimes there are vast differences even within denominations, there is also a variety of beliefs and practices found in this perverse system. Some groups may branch further into sex magik, some may sacrifice animals and not be engaged in any way with the abuse of children, others may skirt the edge of legitimacy with only slight deviations from the original teachings. 

The seemingly second more popular system I found is based on a brand of Satanism twisted in a perverse way out of Christianity and especially the Catholic church which already has in place a set of rituals to be drawn from. Black masses, the belief in conjuring entities and the dead can be shared by both groups but their ritualistic methodology is in some ways different than the one based more dominantly on perverting the Kabbalah alone. They share certain methods and beliefs in the same way Christianity is born from the history of the Jewish culture and tradition, yet Christianity departs sharply with the belief in and focus on Jesus Christ. In this twisted and perverted system there is also a shared basis of beliefs and a departure with the focus being on the Anti Christ. 

I found references to many versions of both of these systems with numerous overlapping methods, but really it is not the point of this article to explore them as neither are by the nature of their existence the ultimate cause of the pedophilia and child sacrifice involved. (imho)

I primarily bring these two systems up because of the confusion I found on the internet about which belief system is to blame for the disappearance of children, their enslavement into sex rings and in some cases the taking of their life in ritualistic sacrifice. Studying this from the USA, where western civilization prevails and information fed to my searches will support the location I am in, I find Jews or Catholics about equally blamed. It is very unfortunate that too often blame is not just limited to those who have departed from the true religious teachings to practice such horrific acts, but the entire group of people who are members of the legitimate religious groups suffer along with them!

I read through site after site making a point that one or the other of these two groups of people is to blame and the same arguments were made in commentary by readers. I am taking so much time to point these things out here because I think only when we stop blaming one or the other groups will we discover what is really going on behind these horrific practices.

For one thing, blaming either group does not explain ritualistic child abuse and sacrifice recorded in ancient history from parts of the world not influenced by the western world or it's fundamental belief systems. If we look back, we see the ritualistic sacrificing of children has been recorded world wide and going on for thousands of years. So, regardless of which ever system may be used today, the idea that ritualistic sacrifice works for what ever end existed in time beyond the development of either of the systems mentioned above, and in places not connected to their reach.  

I don't believe in coincidences and while studying this subject, I "happened" to stumble onto the video I've posted below by David Icke. I had no idea due to the title it goes by that it would contain what I consider to be a reasonable explanation for the question I have been searching to answer.  That is, "WHY?" Why do people practice pedophilia and ritualistic child abuse and sacrifice, and why have they done this for thousands of years? What is it they need out of it, what do they get? To say evil exists for the sake of evil itself doesn't seem like a big enough answer to the specific acts I am writing about. 

To summarize David's comments, the entities - some may call demons, aliens, jinn, gods, evil beings and so forth, use the energy of either sexually abused children or the release of their life force during sacrifice, as their power source. They "feed" off of the release of this energy, if you want to think of it in a different way. The humans performing the acts are their conduits. Trust me; he puts it much better and goes into more details in the video. David explains it in context of quantum physics and using something we can more easily understand, computers and their programs. 

The first video is ran up to the minute where he starts to describe the cause of it. But I would highly recommend you listen to the entire video for a better understanding. I had an aha moment. Maybe you will too. Or, maybe you have a different pov in which case I would love to hear it. 

We can't stop this from happening until we understand and eliminate the cause. If he is right, the cause is in what some may call the unseen or spiritual realm and no amount of working against groups carrying this out on the earthly plane will stop it. 

But what we can stop here on earth, is blaming entire legitimate religious groups of people for their systems that have been twisted by sick minds to serve evil rather than good. 

The second attachment of the video starts at the beginning.
