Just like everything else in life, religion comes as good, bad, and in between.
Good religion builds good mental health.
Bad religion caters to mental instability, encourages dysfunction, and most serious of all, promotes hate. Much of our culture is filled with hate and indifference. Hate is an emotion of gut level distain. Hate makes us do something to hurt others, indifference allows us to do nothing to help others. Hate is what makes people do things like the terrible shooting at the Jewish Community Center in California, the murder of the abortion doctor in New York, the dragging death of the black man in Texas, or the slaying of the gay student in Wyoming.
