they are black in color, their cries are unpleasant, and they eat carrion. These three factors made crows not popular with humans and they have become synonymous with bad luck, especially when they eat carrion. Humans often encounter crows near corpses, which made them known as the messengers of death in some places.
dead corpses are prone to plague, and crows wander around the corpses. This made ancient humans think that crows were people with plague, but the word plague was born in modern times. In ancient times, plague was called a curse by the backward people, and those who carry curses are people who carry bad luck. So, crows that are infected with death and plague also represent curse, bad luck!
I can extract the power of misfortune and give myself the ability to jinx!
I can extract the power of death, and I, the crow, will be my emissary, or I can extract the plague ability.
