The rod of Asclepius (⚕; sometimes also spelled Asklepios or Aesculapius), also known as the asklepian,[1] is an ancient symbol associated with astrology, the Greek god Asclepius and with healing.
Seeing as how that symbol has absolutely nothing at all related to healing, I must agree therefore that is inappropriately placed, and because it is not originated from a Christian mythos, therefor evil.
I mean sure, it's taken from the Greeks, and the founder (more or less) of modern medicine was a Greek... Hippocrates
Yep, must be evil.
Although, if you were to talk about the Caduceus, you would have something of a point.
It's primarily used by the Army and Naval Medical Hospitals.
In later Antiquity the caduceus may have provided the basis for the astrological symbol representing the planet Mercury and in Roman iconography was often depicted being carried in the left hand of the Greek god Hermes (Roman god, Mercury), the messenger of the gods, guide of the dead and protector of merchants, shepherds, gamblers, liars and thieves.
(And, on a mildly interesting note, a fellow named Imhotep (NOT a mummy) founded Egyptian medicine, taking much of the mysticism out of their medical treatments.)
Thought I'd mention this: When I was in Sunday school way back when, we were taught that the symbol stood for the bronze snake Moses put up, that the people looked upon and were cured of their affliction, in Numbers 21:9.
Whether that's just Christians putting a new interpretation on a older symbol (which happens a lot) or one view of it, I don't know.

Moses also used a 'snake on a pole' for healing rituals.
