Are They Good or They Are Evil?

There's all sorts of different levels of consciousness on the spiral that are working their will based on their current understanding. And like you pointed out earlier, they can be technologically more advanced than some of them, but not necessarily morally more advanced. So again, apply common sense, just like you shouldn't join a spiritual movement and assume that the leader is advanced in all these areas. If you are in contact with a group of others or an individual being basic tests, basic common sense, applies across the board.
