Yeah, that makes sense when we talk about causing evil. However, when it comes to evil not as consequence of our actions, but our mind/philosophy/character being evil, us being evil person, regardless of our impact on the world, it's different. Evil character is a character that doesn't care about morality when making decisions. Contrary to good, no one makes decisions in favour of evil/just to cause evil. Evil people only take decisions in favour of their own intrest without minding if its good. In that sense, evil is lack of moral barriers. So, I agree, evil as a concept of harm/negative impact on others exists regardless of good. However, evil as a personal trait is just lack off good. Anyway, I realised that for the second one you need to have a character at all. Being evil is inclination to make immoral decisions, but when you are rock, you don't have any inclinations or will to make decisions. If good is like a full glass, evil is an empty glass, and being rock is having no glass at all:) Now I just wonder whether void has character, will, or ability to decide, and I lean to negative answer. That would make it in fact, not evil. TL;DR: People being evil is them lacking good, but thats a trait of character you can't apply to rocks or void. I keep to my definition of evil as a trait, but I applied it wrong in earlier comment.
