Every service a religion offers can be done without having faith. Religion was started by primitive humans trying to find reasoning in what they don't understand. Now that science has explained nearly everything, we don't need it. The main reason religion still exists is because it is so effective at controlling people.
We don't need religion. In fact, we're better off without it. Even to this day science is hindered by religion (creationism, alternative medicine), religious violence is still rampant (although less then the Crusades era), and an incredible amount of hatred and bigotry (two of the most notorious hate groups in the United States, Westboro Baptist Church and the kool kids klub, are both run by the same thing: Christianity).
Its not just a justification. It also causes this nonsense, and supports it.
You say that our science is so advance that we nearly understand everything, and yet we only know 2.5% of all matter in the universe. Jesus Christ taught these 10 commandments-
ONE: 'You shall have no other gods before Me.'
TWO: 'You shall not make for yourself a carved image--any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth.'
THREE: 'You shall not take the name of the LORD your God in vain.'
FOUR: 'Remember the Sabbath day, to keep it holy.'
FIVE: 'Honor your father and your mother.'
SIX: 'You shall not murder.'
SEVEN: 'You shall not commit adultery.'
EIGHT: 'You shall not steal.'
NINE: 'You shall not bear false witness against your neighbor.'
TEN: 'You shall not covet your neighbor's house; you shall not covet your neighbor's wife, nor his male servant, nor his female servant, nor his ox, nor his donkey, nor anything that is your neighbor's.'
How are the teachings of Christ immoral and controlling? My relegion teaches us that it is through our good works and faith in Christ that we gain Eternal life, how does that harm society? Your saying that that harms society by making LDS people do good for others? I don't think so.
As I have said before concerning a group, by saying that Christianity is evil becaues there have been some bad apples in the bunch, is like saying that all Americans are evil because our ancestors slaughtered Indians.
