Origins of good intentions

Scientology has been getting a lot of bad press lately, to be honest I can't say I know all that much about it, I'd come across it now and then but had never really given it much thought until some online friends had begun mentioning it in their art and such.
I'm not going to say anything about what Scientology is as I said I don't know enough about it, however I was intrigued by this one line from it's origins.

"A civilization without insanity, without criminals and without war, where the able can prosper and honest beings can have rights, and where man is free to rise to greater heights, are the aims of Scientology."

Reading a little about it's origins, to be honest saddened me because from what I could see this was a religion that actually sounded like it had high hopes for humanity. In that one line we are given a great deal of good points, I'm all for humanity being able to rise to 'greater heights'.
Again I don't know everything about scientology but from the sounds of it, it's not taking anyone to 'greater heights' or just it's select view at a cost to everyone else.
It makes me wonder how many religions and groups set off with good intentions only to be infiltrated by malicious agendas.

I have heard such things about the freemasons, when you look at the early history it all sounds pretty good to be honest, they were an important group and did have some important secret or knowledge that they were to protect. Sadly however it seems that they were infiltrated too and that secret has been lost leaving the group a mockery of what it once was, it now seems that it is nothing more than a place to keep the well thinking men of this world in their place, the very people that could save it from true evils.
In George Orwell's 1984 the thinkers of the world are keep under control, they are watched 24/7 and any sign of rebellion is quickly dealt with, where as the lower classes of people are left to get on with their lives as it is seen that there would never be any trouble from them.
Free thinkers in this world are always suppressed or removed from the world all together.
Any good ideas or groups are infiltrated and turned in to something black and evil, it's easy to do it that way than fight against them I guess.

I don't think such groups or religions are ever set up to be something that is going to be bad and controlling. I think someone or something finds it's way in to them and twists them in to something they were never meant to be.
I once considered myself to be wiccan, however when I look at websites about being wiccan and am told I need to pass tests to become wiccan I find that a little odd, why do I need to pass a test to prove who I am? Wiccan used to be something you just were, you didn't need a piece of paper to prove it. I think someone has taken this and decided to change it's nature in to something else and I hate where I see it going.
I chose the title 'wiccan' because it felt the closest to what I was, I now know that what I am doesn't need a title, I am what I am and no one can infiltrate that.
