Yes I'm new, and I don't know why but I had to tell people this (I got stuck on the topic) but I think FMA may be actually really deeply linked to satanism. I discovered this possibility by talking to a friend that is satanist. In the religion a homunculus is, like in the anime, created by the failure of a ritual that is used to create an artificial lifeform. The Ouroboros is also a symbol of satanism (the dragon biting its own tail) Not only that but the upside down pentagram is also in alot of the transmutation circles. Like I said abouit the homonculus the 7 pointed array used to commit human transmutation is the same array shape used in the ritual. Also in the religion alchemy is the act of taking human souls and basically feeding them to satan (human sacrifice as seen in a few movies and other animes) thus completing his work.
Please tell me what you think of this?
As I just learned if you look up "Ouroboros Satanism" on google images and if you just look at the goat in the pentagram image you will find that in most of them the ouroboros mark is what surrounds the goat in the pentagram. The ouroboros mark afterall does really mean "none ending" which would explain why the homonculi cant really die, since they have the tatoo (in the second series).
Also the goat that is inside of the upside down pentagram is called "Mendez: The god of LUST" Lust being one of the homunculus.
