I’m sure something similar to this, or perhaps exactly like this, has been posted before, but here is a thread to talk about your ideas of good and evil. is there a spiritual realm, if so, do the forces of good and evil battle eachother constantly? Do the forces manifest themselves in the temporal realm? penny for your thoughts.
Is this a trick question? Are you asking if Star Wars is real? 
Without one, the other cannot exist. Life tends to be somewhere in between. I do not think a spiritual realm is required for this concept to work.
Meh, it’s all relative to the person.
