does U think God will forgive atheists?

There is no proof God exists.

Why would I care what a mass genocidal maniac thinks of me? He should be asking us for forgiveness.

The Flying Spaghetti Monster, Creator of us all is merciful and kind.  May I bask in his Sauce for Eternity! 

Do, not does. Learn basic grammar, fool.

Will God forgive me for helping myself to the charity boxes in a church.

Yes. If they repent before they die.

When God says “their sin I shall remember no more,” he is assuring us that once he forgives repentant sinners, he will not at some future time act against them because of those sins. (Ezekiel 18:21, 22) Jehovah thus forgets in the sense that he does not bring our sins up again and again in order to accuse or punish us over and over.

As long as atheists don't hurt God there is no problem at all. They must understand that believing in God is just like providing an antivirus to a computer. If they are not careful in their lives, the evil may possess them easily and put them in trouble.

God never bothers whether people believe in him or not. God’s involvement in human affairs is very rare. God doesn't watch each and every human being at the same time and cannot live with each and everyone to guide them. These works are done by the spirits. God had created different kinds of spirits for various purposes. He had made the spirits to watch, guide and determine the destiny of the human beings from their daily activities, talks and thoughts too. Your past determines your present and your present determines your future. God has given freewill to all creatures including human beings. According to this, all human beings have all right to live a life as they wish. But if it happens to be bad and hurts someone, they have to face the consequences. These consequences are created by spirits. It's a natural system. After death no one lives in any form. Heaven and hell are only for spirits, not for human beings. God is a mystery even to the spirits. Spirits are not eternal beings but their lifetime is long. Spirits are separate elements. A human being during his/her lifetime is living with many spirits which have joined one by one since birth. They are knowledge, skills, feelings, emotions, interests and everything. These spirits are your consciousnesses and memories. Even thoughts are not your own. For example, when you want to take a decision on a subject, one after another the spirits think and you just listen, choose or reject the ideas which they transmit to your mind through your brain in the form of thoughts. Brain is just a media to connect the spirits to your mind. A mind is just a computer's mind. A mind is you. After the destruction of a computer completely you will not get it's mind. The same is the case with the human beings.  A human being doesn't have a spiritual body. Soul is nothing but an energy needed for the functionality of a body. It is not a spirit or anything else. A body's functionality is based on the auto mechanism.  After death all spirits which accompanied a person quit and go to different places searching new bodies. No one lives in any form after death. All human beings are just robots made of flesh and bones and toys of the spirits for their games.

If they repent, yes.

Not unless they repent of their sins and exercise faith in Jesus Christ as their savior and do God's will, otherwise they will perish along with the billions of people who have no place in God's Kingdom. Prophecies of the Bible and the times we are living in are proof enough of God as the Prophecies written thousands of years ago are unfolding before us and there is no denying that. That why they are considered fools. They won't admit to it or see to save their lives.
