Hi kateWild. I think beliefs can harm people and they can also help. In a way harm and help are relevant in terms of what the real truth about existence is anyway. Thus the same can be said regarding atheists also. Of course we live in a physical universe and so atheists will often do a bit better than believers for that reason in many ways. I could real of a list of atheist virtues at this point but I am a believer. So to me the question of an afterlife comes to mind. If this is the case then this physical dominance may be reversed in the future when we die or when the universe itself comes to an end. This only applies if there is an afterlife of course and the best way to search for an answer is to look into the realms of spiritual beliefs. It’s very `chicken and egg` in a way, if one looks at it only from the perspective of this life.
Take good and bad for instance. They seem to be dependant things in that one can’t have good without bad, or bad without good. Looked at logically and In terms of itself, it is impossible to come to an answer. Take the concept of up and down. The reason for up is down and down, up! They exist as co-dependent concepts that cannot be separated. However if `up` didnt exist one could not travel in a direction and holidays would be impossible. If however I was to say straight out that `up` exists in order that people might enjoy a holiday, people would not see any link between these two different things because there is a tendency to look at concepts only in relevance to itself. Logical loops are easy to get trapped in. Any resolution normally comes from looking outside the logical loop.
So on a universal level with the question of evil and the idea of God, the answer may well exist outside of this life and this universe. It depends on the truth of the question as to if God exists or not. Good and evil constitute a logical loop and thus an answer will not lie there as to Gods existence or not. Other things depend on good and bad existing which might give more clues on the matter of God of course including evidence that other realms exist or not.
Just a few thoughts I thought you might find helpful or interesting.
