Shouldn't Christians hope they are wrong?

There are a bunch of things that Christians believe that I find hard to swallow. Yes, I was once a Christian so I can understand how they HAVE to believe these things in order to maintain their doctrines, but I wish they would consider, as I have, that they may be wrong. Some of these things they believe are so terrible that it should compel them to hope that they may be wrong. For example, if I believed that an ancient people prophesied that in three years the world would be impacted by an alien missile that would send the earth on a collision course with the sun and that subsequently every living thing on the planet would become fried - Shouldn't I spend all my time trying to prove myself wrong? Christians also believe that one day billions of people will fry in the flames of hell, but they take it another step further and make it last forever. What an awful thought. Shouldn't this compel them to hope that they are wrong? Shouldn't they be reading all of the critical books that have been written against their religion? Shouldn't they be researching all of the scientific discoveries that may contradict what is written in their holy book? It may dash their hopes of one day reaching their eternal paradise, but in my opinion that is a small price to pay.

A man may spend his life inventing medical cures that save the lives of millions and prevents much suffering, but in the Christian worldview, if he did not believe and dedicate his life to the god/man Jesus then he will spend an infinite number of years wailing and gnashing his teeth in unquenchable flames. 

According to Christian beliefs, I would have been infinitely better off if I had died in a car accident while I was still a Christian than later abandoning my faith in the religion and one day reaping the consequences. 

I'm sure if you asked most Christians they would say that aborted babies all end up in heaven along with miscarriages and other infants who die young. If this is true then, according to Christian beliefs, all of these babies are better off dead and in heaven then having to live here on earth and possibly not becoming a "real" Christian.

Christians look forward to the day that they can leave this earth for a better home where they can eternally be at the feet of Yahweh, worshiping him forever. Unfortunately they have to do this in spite of being aware of his deeds in the Old Testament. Yahweh was at one time fed up with people so much that he drowned a world full of them including plants, animals, children, elderly and everything that breathed. Yahweh also commanded his chosen people to annihilate the people who lived in Canaan and would not allow them to spare anything that breathed (except a group of virgins once). I'm not sure which was worse: being killed with a blunt sword or having to be the one doing the killing. Why do they want to believe this with all their heart? Because Jesus fixed all of this? 

Jesus had some good ideas, but he was not perfect. He supposedly said things like: "Think not that I am come to send peace on earth: I came not to send peace, but a sword", "For I am come to set a man at variance against his father, and the daughter against her mother", and "All these things are done in parables: That seeing they may see, and not perceive; and hearing they may hear, and not understand; lest at any time they should be converted, and their sins should be forgiven them." If you think that's not so bad, read about what happens in the book of Revelation and I doubt you'll think the New Testament is a nice book anymore.

In a last attempt modern Christians will re-interpret every passage in the Bible that they have a problem with, they will focus on the social aspects of Jesus' words and Paul's writings, and they will try as much as possible to become relevant for the culture of today. Even this modern version of Christianity should raise some eyebrows. Most modern Christians still believe that the majority of the world is going to hell. Most of them still believe that human sacrifice is a medium for appeasing their god (thankfully it was a one time deal). Most of them still focus on the brutal act of a Roman crucifixion and focus on a broken body and spilled blood. Most of them still believe that any day now the world and everything left in it is going to be destroyed and remade. And most of them still become self-righteous and tend to look down on anyone who does not believe what they believe. All I ask is that they open up about their doubts and become honest with one another. They should be open to other points of view. 

If humanity is going to thrive in the future, things like bigotry and intolerance need to be set aside. Superstitions should be cast off. Apocalyptic and doomsday thinking should be kept in check with reality. Attempts at finding the truth of a matter should begin with evidence and probability and should not be based on dogma and presuppositions. The value of life must be upheld. Suffering should always be avoided. People should be kind and thoughtful to others because they want to, not because they want to gain an eternal reward. I'm not saying anything new. This has all been hashed out many times before. The question is, do Christians deep down really hope they are right about these things? Shouldn't they hope to be wrong?
