Evil witches are all over the world, but they are now living undercover, never showing their powers again. That is unless they want to suffer the consequences that the order has already warned them about. Witches possess the power to control the masses and be the rulers of the human race, but none of their spells work against the order and we have enough intelligence and enough power to destroy all of the witches if needed. We chose not to because we believe that they are higher forms of human evolution that are able to use dark forces and understand the spiritual world completely.
They might be useful in the future and with the laws we have imposed on them we are sure that they will remain in the shadows as far as their powers are concerned. We do think that they are more valuable than the average human because of their ability to cast spells that normal people don’t even believe to be real.
