They value self-satisfaction above most everything. That its not a sin to give in to temptation and pleasureful things. It is not an evil religion because they do not believe in harming others UNLESS they are harmed first. etc.
That a mere creature, and a loser at that, can offer you more than the Creator. And that loyalty to one who desires only your eternal destruction is a smart idea.
You have to understand that there are lots of different types of Satanism. Some Satanists don?t believe Satan is even real and other think he is real. There just to much to dot down here. Spiritual Satanists believe that Satan is real and he created us along with a few other Gods. Also they believe he is not evil at all. This evil thing comes from Christians. Satanism is one of the first religions on are planet and lots of religions after it where shaped in its image. You should research the different types.
A couple points of view here.
Some believe the "Satan" was a name given to a much older god. The one that actually did create life. Xianity plagiarized much older religions, forced others to convert or die, then destroyed the evidence of the occult knowledge given to man by Satan, or Lucifer. This knowledge was to help mankind elevate then selves spiritually to the point of being gods themselves.
There are some Satanists who don't believe in any of sort of Deity at all. They usually follow the works of Lavey and are basically atheistic in their belief system. They worship themselves as being gods already, and their motto is something akin to "do what though wilt, shall be the whole of the law". They also teach a healthy dose of responsibility to go along with their doctrine, pointing out that it is only favorable to be responsible to others who are responsible for themselves.
Oh and please for all of the above posters, Lavey had his moments but he did not by any stretch of the imagination invent Satanism.
We teach that we are Natural beings, and as such, should do what comes naturally.
We teach that all the seven deadly sins are falsehoods, as they all lead to mental, emotional, or physical gratification. I could explain this in detail if I have to.
We also teach responsibility, that we are responsible for our own lives.
We teach that animals and children are sacred, as they are Natural in the most complete sense as they have not been sullied by the likes of preconceptions.or interference from humans in an animals case.
We teach to love completely they whom deserve our love,and to hate they who would wish us ill, for then love and hate won't become watered down, by trying to love everyone, even people that do rotten things.
We teach to learn all we can about our natural world, to learn history and symbolism, so that we can better connect to Nature.
We teach an understanding of all the forces of Nature, and how to balance those forces within ourselves.
We show that self-preservation is the highest law, as if you cannot preserve yourself, then how you can preserve anything?
And we show how to ritualized our emotions into magical workings, to accomplish something that would otherwise be unchangeable, and to rid ourselves of emotions that if held in could destroy us.
We frown upon drug use, as that makes a person less effective as a magician and a human being in general.
Uuummmm.....I could go on....feel free to shoot me an e-mail!
