Hello all. I am very much new here, and this is my first post.
I signed up to fulfill the OP's desire to see somebody in these forums answer these questions. However, as an atheist, and as a new member, I am not sure that I am meeting the standard which he intended.
Anyway, here we go.
1. Tell me what you think evil is.
This one is particularly fun, as evil is something which is very difficult to explain in an objective manner. Perhaps the OP does not want an objective answer, however. Evil is difficult to label for me, because understanding actions requires an understanding of the person committing said actions. There are too many variables involved in answering this question, and I would need to do so in an essay format in order to be satisfied with my answer.
2. Do you think the existence of evil and suffering is a serious obstacle to belief in God.
Considering the spelling of 'God', I am made to assume you mean the Christian god of Christianity's holy book. As previously stated, I do not view evil objectively, so I can not answer this question in that regard. I can, however, answer in regard to suffering. The plain and simple answer is "no".
After reading the Holy Bible, I have no objection to his existence and the existence of suffering. In fact, it seems as though the Christian god, as portrayed by the bible, enjoys suffering on Earth.
My problems with suffering and the existence of god only come in to play when I am faced with the image of the Christian god as he is seen by many modern followers. At least by the majority of those who attempt to convert me. This image, of course, is that of the personal, omni-benevolent creator being who loves all of his creations as a parent. I am sure that I do not need to spell out my view on this any further.
3. Do you think that free will explains most of the evil in the world.
The answer to this question relies on one's personal definition of evil. I would say "no".
My reasoning is that many of the acts which I come to know of in my every day life can be rationalized through investigation of the individual committing the acts.
For instance: Middle Eastern suicide bombers could easily be picked out as evil. And one could say that they choose to commit the acts they do.
The distinct line of evil becomes blurred, however, when you try to see these decisions from the eyes of the one taking action. These people believe that committing these acts, which I see as terrible, are the best thing they can do in the eyes of their god. To top it off, they are raised from childhood with a glorified image of this.
Can you easily say that if you were raised by your parents, from the day you were old enough to understand language, to think that it is okay to steal and cheat and lie, and that it is what you must do to survive, that you would choose freely to not do so?
My personal opinion is that the most evil deed committed is that of parents teaching their children what to think, in stead of teaching them how to think. And this act does not require a god, nor does it require, or even leave much room for, free will.
I apologize if i strayed from the original point of the question on that one.
4. Is your atheism a result of personal suffering, or the suffering of a loved one? If yes, could you share what happened? If no then why do you not believe in God?
The plain and simple answer to this is that I have never believed in a god. Not the Christian god, not the Muslim god, not the gods of Olympus.
I apologize in advance for this deviation from the point, but I feel that I must explain that I never made a choice to not believe.
If you will allow, I want to enter in to record a personal anecdote. Take it or leave it, it's up to you.
When I was all of seven years old, I was riding to school on the big yellow cheese, and a friend of mine, who I am still friends with to this day, eighteen years after, was talking about his religious beliefs. His beliefs being Christianity, particularly Roman Catholicism. I don't remember the exact question he posed to me, but I do remember my response. In reply to his question, I simply stated "I don't believe in god." His reply was "Well, you're going to Hell in a hand basket." A phrase I had heard numerous times by that age, though not always directed toward me.
The point of that statement was simply to show that I had an active stance of disbelief in the supernatural from a very young age. It was not something I chose, it was simply my state of mind.
5. Why do you think that atheism better explains the problem of evil than theism?
The question posed is too broad. Theism is simply the belief in a god or gods. Evil can be viewed in so many different ways depending on what god to which the individual subscribes, and even then, the definition of evil can change depending on whether it is an individual or a society which believes in said god.
Atheism is simply the lack of belief in a supernatural god being.
And even were the question posed in a more direct manner, there still exists the variable definition of evil.
Perhaps a better question to ask would be if suffering can be better explained by the existence or non existence of the Christian god.
I will not go in to detail on this question, as it could easily be misconstrued as an attempt by myself to set up a strawman, which I have no desire to do. I will check back to see what you guys think of my reply, and If the OP chooses to reword this question for me, I will attempt to answer it.
6. Some have said that the comfort from religious belief is that no deed done goes unnoticed from God, and that even if they "get away with it" from the eyes of justice, they will still be held accountable with God. Does the possibility of real justice (from theism) make it a promising way to look at the problem of evil?
Good one. I would have to say that I am more sickened by this than comforted. For one, this allows individuals to shirk the responsibility of seeking justice against those who have transgressed. Second, this makes your god seem like more of a police force than a parent. Also, I see this as a problem because the justice of the Monotheistic god is simply tyrannical. Eternal punishment for a finite transgression is simply too much. The point of punishment is to show the recipient his wrong doing, and to change behavior. Eternal damnation achieves neither of these goals. Besides, does it not seem to anyone else that we, as a society, are more interested in punishing the wicked than we are in rewarding the righteous?
Another problem I have with this question is that it seems only to focus on evil. In your question you state that "no deed done goes unnoticed from God", which is simply a lie. As an atheist I am constantly bombarded by the assertion that if I do not believe in, repent to and accept as my personal savior, the Christian god, then I will forever burn. This punishment fails to take in to account all of the good deeds I have committed, regardless of the fact that I do not believe that I will receive any reward for doing so.
So simply, the statement that "no deed goes unnoticed by God" is a flat out lie. It should be reworded to properly imply that no wicked deed goes unnoticed.
Once again I apologize. The end of that might have seemed somewhat like a rant, but I have become somewhat embittered toward religion over the years because of the persecution I have received for no other reason than not sharing the same set of beliefs. I can only imagine what it is like for those who live in regions of the world which are less tolerant of disbelief in the current prescription.
Anyway, thank you for your time and consideration.
