Infallible
I believe that humans can become infallible and this is the reason we were created, but we still cannot find a way to get to this stage, because we all disagree on our each religions or beliefs.
Also, I believe that each religion has its own way to get to this level by practicing and training their souls to not to choose the bad habits and going the opposite of what they prefer and like, because sometimes what we love or prefer could be wrong and bad.
