I think God put them throug the suffering to see if they would stull put their trust in him.
There were many times in the bible where God tested his followers. It is the hosen land but does that mean it wil be right now, or million years later?
I think its beautiful, and no one has the right to take that away from them, believe away, and it might pay off in the end. Whats the harm in someone who wants to believe in something more?
Unfortunately, there is a lot of harm.
Look at what Christianity has done to black people and homosexuals. Look at how often certain Muslim sects declare holy wars.
Personal belief is one thing, but enforcing your opinions on to others, or propagating your own opinions at all is probably a bad thing.

A religion (by definition) is a spiritual relationship between a person with a deity or a supernatural being (or an apparently supernatural being).
This relationship, in most cases, helps society as much, if not more than it hinders it. The rules about food are obvious: some preparation of food is more hygienic so cultures which command this religiously grow and so does there religion. Resulting in better hygiene for that entire regions population. The Muslim rules about cleansing yourself (washing) help sanitarium as well. Also most religions have good meanings within them which most believers focus on, like love and forgiveness in Christianity as well as helping the poor (Jesus did all these things whether out of holiness or out of being a good guy in general). I am afraid I don't know the central moral teachings of many other religions (respect for nature in Hinduism and lots of really truthful stuff in Buddhism).
People can go to war without a God and would probably go to war no matter what. If someone came to you home and lynched your family (sorry for grotesque imagery but this needs to be emotive) you would probably think they were evil and that it was morally right to kill them or have them punished. a Christian would believe they should punish these people because of the Ten Commandments. A Muslim might claim it was for (I don't know if typing his name without proper techniques is acceptable I know Muslims find portrayal of holy things a difficult subject).
I think it was the economic philosopher Karl Marx (also known as the father of communism) who wrote: "religion is like a drug" and I agree with him to a point. Drugs would be fine if they didn't cause sane people do dangerous things and hurt others and many drugs eventually end up killing the addict by an overdose. Have you ever seem anyone have a fatal fit from reading the bible too much? Such in some churches they crawl along the ground and pretend to be dogs but they don't tend to die as a result. I am not saying religion is harmless, just that it relatively harmless. Oh course there are crazy preachers but they were usually sane beforehand.
On the other hand this could be said about the good things people do for religion and you could argue that all charitable missionary work would be done by the same people if religion never existed.
Religious distress is at the same time the expression of real distress and the protest against real distress. Religion is the sigh of the oppressed creature, the heart of a heartless world, just as it is the spirit of a spiritless situation. It is the opium of the people. The abolition of religion as the illusory happiness of the people is required for their real happiness. The demand to give up the illusion about its condition is the demand to give up a condition which needs illusions.
I think you are trying to shoehorn religions in to an idealised definition. In the real world a religion is much more than just a relationship - it's an entire system, a doctrine, an institution.
