All right. I'll ask you to actually look at what I have to say before telling me it's worthless bullshit next time, though. I don't mind having intelligent conversation with somebody with differing opinions than me, I just like it when they at least hear me out before shooting me down.
It's not necessarily about God and the Devil. I, myself, don't really Christian writings literally. But there *are* valuable lessons to be learned from them. In that sense, religious scriptures are like fables (i.e. the tortoise that outran the rabbit). Should you take them literally? You don't need to. Should you at least think about the meaning behind the story? I think so.
The non-literal interpretation of this Satanist philosophy emphasizes the importance of freedom in society.
For example: If a husband beats her wife and tells her he'll kill her if she ever leaves him, does it mean anything if the wife doesn't leave him? No. If she stays with him, does it mean she loves him? No. If she's staying with him, it's probably because she's terrified out of her mind, and not because she actually loves him anymore.
Another example, one that has slightly more real-World applications: Let's say we have a mob boss/gangster. He's oppressive, threatens his people with violence. He demands unreasonably ridiculous amounts of protection money. He sells drugs to kids. Now, will the people follow him? Yes, but only because they don't have a choice.
Now, let's say another mob boss comes into the neighborhood. He's closer to Robert DeNiro's character from The Godfather II movie, if you're familiar with it. Is his operation legit? Yes. But whenever somebody's in economic trouble, he takes it easy on them. Whenever somebody is bullying somebody else in the neighborhood, he steps in and works to find a compromise for both of them. He's fair and almost never resorts to violence. He doesn't support drug dealers who sell to children.
Now if these who bosses go to war, who will have more support? The second one, obviously. So who will win the gang war? The second one. If the civilians have to choose who to support as the local mobster, they'll choose the second, because they know that if he wins, they will have much better lives than before.
In short, if you're fair to people (friends, parents, family, people who work for you, etc.), then you will be loved by everybody around you. If you're a dick and you do everything you can do hurt somebody else, then the instant somebody else comes along, they'll bolt and you'll be left alone and everybody will know not to trust you or give you any sort of power over them.
