Aberration

An aberration is a thing that is "other."

Aberrations are foreign. Alien. It is a category of the uncategorizable. They don't seem to make sense. We don't know what they're about, so we toss them all in to this category.

Most of them are extremely dangerous. It's not necessarily because they're malevolent, but rather because their morality is so utterly alien to us that they often come across as capricious and malignant. They do horrible things in so nonchalant a manner that we cannot help but interpret them as evil.
