Odin the “All-Father,” chief of the Norse gods and leader of the powerful Aesir was unmatched in magic, cunning, and battle prowess. Attended by his raven familiars, he sacrificed his own eye in his quest for knowledge.

NORSE GOD
Odin
By Thomas Apel
Widely worshiped by the Germanic peoples of the Middle Ages, Odin, furious lord of ecstasy and inspiration, was the highest of deities and the chief of the Aesir tribe of gods and goddesses.
Known as “all-father,” among many other epithets, Odin was usually depicted with one eye and a long beard. He would often be accompanied by his familiars—the wolves Geri and Freki, and ravens Huminn and Muninn—and rode an eight-legged horse named Sleipnir.
Befitting his kingly stature, Odin was also a mighty warrior—it was said that he never lost a battle; there were even some who believed he could not lose a battle.
===============================================
Just because someone wears something related to Norse mythology, it does not mean they are involved in ritual sacrifices, or violence in any way.
People routinely wear symbols of their cultural or religious ancestry, and the Germanic peoples of the Middle Ages are ancestral touchstones for many people.
If someone wears a patch referencing Odin, that does not make them automatically menacing cult members.
