I doubt it, they are aliens as for evil, at some point they did caused some fair share of extinction. When they started to grow roots, causing minerals getting thrown to the seas creating deadzones killing a lot of life. Their ancestors likely algae who produced oxygen so much that killed of a lot of life that relied on low oxygen environment. I guess that could be considered evil. But then again they were not aware of doing it, and this process took millions of years. On the other hand here we are speed running to extinction. While being aware of doing it lmao 🤣.
