Ooooooh. I think I understand. Not ALL are bad, just SOME. It's going to be biblical. That would explain a lot of things.
You have turned my fathers house into a den of thieves.

The double snake is the Hermes one, NOT the single snake. Hermes was the god of Commerce, not medicine. The middle image was the brazen serpent that Moses had fashioned when the children of Israel were being bitten by snakes in the wilderness and all who looked upon it were healed. It represented Christ becoming sin and paying for our sin. It was a foreshadowing of what Christ was going to do. Brazen objects represented sin.
Nehushtan
In the biblical Books of Kings (2 Kings 18:4; written c. 550 BC), the Nehushtan (Hebrew: נחשתן Nəḥuštān [nəħuʃtaːn]) is the derogatory name given to the bronze serpent on a pole first described in the Book of Numbers which God told Moses to erect so that the Israelites who saw it would be protected from dying from the bites of the "fiery serpents", which God had sent to punish them for speaking against him and Moses (Numbers 21:4–9). In Kings, King Hezekiah institutes an iconoclastic reform that requires the destruction of "the brazen serpent that Moses had made; for unto those days the children of Israel did burn incense to it; and it was called Nehushtan". The term is a proper noun coming from either the word for "snake" or "brass", and thus means "The (Great) Serpent" or "The (Great) Brass".[1]
