The Watchers, who appear most extensively in 1 Enoch, are angels, but they seem more demonic through their actions. Their first evil act was to transgress God by taking wives on Earth. They acknowledge that this is wrong in the text, and know full well what they are doing. The Watchers were sinful and evil because they transgressed God’s commandments. The Watchers, while on Earth with their women, are said to have taught humans many things that humans were not supposed to know.
