-1- What is your view about the afterlife?
I have no memory of being dead in the afterlife, so anything I think about it is speculation. I do think that people who contribute lasting influence to their cultural group live on, in a way, and there may be some survival of consciousness involved. Dunno, really.
-2- Do you believe Jesus and the God of the bible exist?
The Bible is a vast religious record showing combined influences of several cultural groups from millennia ago. IMO, it says no more, and no less, than any other such artifact does about the Deity, insofar as humans at this stage of our development can comprehend what "Deity" might be. The God of the Bible and Jesus, at this point exist in the forms of many egregores -- concepts developed and changed over the centuries by various groups of believers. And maybe nonbelievers as well.
-3- Do you normally feel happy in your life?
I feel happy about things that make me feel that way. I think that is fairly "normal".
-4- What made you follow the left-handed path?
The LHP is not something you are forced to follow by an outside influence. There is no religious conversion process involved. I think LHP is something you are by your nature, but the choice exists how far to develop your natural inclinations.
-5- Do you like Satan for what he is and what he does?
The LHP may, or may not, include the concept of Satan as an important archetype. Personally, I don't use Biblical references -- including "Satan" -- in my spiritual life, as they are culturally alien to me.
-6- What are the morales learned. Are they all about selfishness and greed above all?
In ny view, the LHP is not about learning morals. Ethics are essentially cultural, but modified by individual life experience and each person's unique vision. Some contemporary LHP groups throw around words like "selfishness" for their own reasons, but I am not a member of one of those groups so I cannot properly represent their points of view. You can read about these topics in threads here in the LHP DIR and in the Satanism DIRs. Greed is what it is, and as far as I know, is not a virtue (?) in any religious community.
-7- Do you support/enjoy child sacrifice?
I suggest you do some reading right here at Religious Forums about the LHP and/or Satanism, and then come back with a reframed question if you wish to discuss topics like human sacrifice.
-8- Can you summarize what Satanism is all about? Because from my own experience, each one described it differently than the other.
Again, the LHP is not necessarily a path involving "Satanism". Here on REF, the DIR areas for LHP and Satanism are separate. Not all who consider themselves Satanists are LHP, and not all who walk the LHP are Satanists. I am not a Satanist, so I don't feel qualified to comment.
