The reason some people feel bad is that they do bad things and most holy writ puts the spotlight on human depravity and other forms of shortcomings. The purpose of religion is to make people better not just feel better. As long as human ego is on the throne, there is no room for God. The gospel is foolishness to those who are perishing. Those who are on a spiritual quest should ask themselves,"Am I really on the path?" Or am I just wanting some supreme being to bless my own ego-centered agenda? Feeling bad means you may be at the crossroads. Then free will becomes the issue. It wont be easy,but it is possible to make the right choice if you ask.
