That, or pretty much any LHP-religion. Just because you don't want to work with the mythology normally associated with Satanism,
@Sheon, you don't need to rule out its philosophy with it.
LHP-religions are about choosing what works for you, so if someone feels better in another set of myths, they can use that as well.
Actually, even many who call themselves Satanists tend to utilize other myths more than Abrahamic ones.
I agree, but it's a matter of what we understand by hedonism.
And I'd argue that serious adherents of a hedonistic philosophy don't strive for pleasure at any cost, but rather for a balance between what they'd enjoy now and what is best for their goals in the long run. Else they could simply become drug-addicts.
Again, LHP. There certainly are also other religions that are compatible with that, but the (western) LHP is explicitly focused on self-improvement and finding what makes you you.
It's often not really associated with helping others, but it certainly won't hinder you from doing so if you want to, on the contrary,
Therefore immoral = things that hurt oneself?
