The main point is that if majority of the people are smart and intelligent the evil or the bad energy will go by it's own because what I have seen is that intelligent people don't focus upon these kinds of things.
The way you mentioned that if you were significantly more intelligent, I really appreciate the way you want to improve yourself significant and evolve more but being more intelligence or gaining knowledge isn't the main focus for living it's actually how we use our current knowledge effectively because no one is perfect, you still have some sorts of flaws within yourself.
