I disagree.. Child molestors think "this works." But that's clearly wrong... Murderers also think "this will work. " but that's clearly wrong as well... What's works for one doesn't work for all..

It is a mistake to assume religion deals in right and wrong, or good and evil or even morality and ethics, they do not.
Religion deals in Sin and Virtue, based solely on what their particular cult deems to be the preference of that particular deity at that particular time.
This is extremely useful, especially at times of war, or social rebellion.
For example if you want your flock to be in fear and crippled by guilt you find something completely natural and harmless that almost everyone does everyday and declare it a sin in the eyes of god.
This immediately has a number of effects

1. It sets up an unpaid virtue police of people so determined to prove they are not sinning they will report those who they think (or want to think) are.
2. the guilt ridden will confess and leave themselves open to black mail if they do not atone
3. People will pay for forgiveness.
4. An appropriate punishment can be set, so instilling fear and obedience.
5. A virtuous hierarchy can seize power on deserved merit.
6. Natural disasters can be blamed on the sinners.

This why most new religions immediately have a list of prohibitions for perfectly natural thing such as tea, coffee, pork, beef, homosexuality, masturbation, premarital sex, dancing or even chocolate.

Conversely utterly horrendous things can be made to be virtuous and pleasing to god such as aversion therapy, forced purchase of religious items such as e-meters, mass suicide, prosperity gospels, exploitation, hating people of another religious persuasion, invasions of promised lands and the genocide or enslavement of the people already living there and extermination camps.

Religion has nothing to do with good and evil, right and wrong and morality in the pragmatic or ethical sense at all, as I said it is all about subjective Sin and Virtue.
