Nobody here can say if he's a Satanist or not, truth to be told , nobody can know or at least not yet but more importantly you should understand that the best information about Satanism you will found it here. As per the most things you've said that he said , I agree.
I think each one of us has some part of Satan in ourselves , some having the 0.00001% of 'Him' but without over complicating things , welcome and you can find any kind of information here, in regards of many things. Take your time and read the entire purpose and meaning of what Satanism truly is.
Start studying the site and the forum in depth , ask questions , search around.
We should stick for each other and be together but one cant simply love blindly anyone close to him as the other false religions are doing , this is madness , you can't simply love or trust somebody you've met one second ago , although we are pushing and striving forward for prosperity , power and success in all of it's greatest potential, in today's time one should be cautious what he says and to whom , one should not truly trust anything and anyone beside his own intuition and guts.
There's a lot of misconception about Satanism that needs to go and fade away.
Somebody today showed me a video of some problematic 'modern day issues' where they tried to obviously as usual , regardless of which religion it is, blame it as always on the 'Demons' and Satan , when , in a matter of fact , for a fact, Satan killed 0 people in the christian Biblie, Satan existed thousands of years before Christians, Jews and Muslims and many other way older civilizations and religions. And I have said to this very person " Hmm.. strange how you're promoting the very thing that makes the entire world sicker then already is" and then he proceeds showing me a video of somebody praying in a Church , as in like if you're going out and doing bad deeds and then going onto some church and pray all of the sudden your entire karma is washed away and you're ultimately forgiven by the Universe itself , that's illusions and crap sold to keep the open minded and visionary people as us away of the true purpose of existence.
I always and will forever look towards achieving greatest perfection that there is, regardless of how many of thousands of hours and even life times I got to work to achieve the GodHead , no matter how much it will take , it's worth the effort and pays up the biggest Win in the entire Universe , what else to spend my whole existence if not just this very thing ?
Satan has been portrayed as bad and the opposite of what He truly is when in fact Satan is the true God of Humanity which stands for each individual equally wanting all of us to grow stronger then ever and achieve our greatest potential in this Universe by progressing , He is the God who releases everyone from enslavement and gives you the Freedom to be You and do You for as long as one follow the Universe's Law and action accordingly .
