Same for fairies. Some are good, some are naughty. There's health and balance there, and a lot of ignorance from people, so depending on the people's mental state and spiritual dissonance you'll hear different stories about the fairies and fae. It's why they traditionally look broadly similar, but a fairie can look like a typical happy bright high elf with cute wings, and another looks like a desolate hobgoblin with dead baby blood dripping from the corner of his mouth.
They all have their places in nature. The problem is that the Roman church sought to define and dictate nature through the lenses of regressive Atenist deception as handed down through the cult of Ishtar into the council of Nicaea.
