It's too predictable. I'd go with something different, a Druid who is evil not because of their beliefs, but because they sold them out for personal gain. Like a Druid who pretends of be a protector of a forest to trick people into a situation where he or she can sell them to slavers.I've always wanted to do a militant nature's rights activist. Bent on destroying civilization and returning to a hunter/gatherer society. Freeing horses from stables, and animals from farms. Burning down remote homesteads. If the druid had enough power, destroying small towns.
