Your soul leaves your body the moment life does. When you die your soul returns to god and you cease to exist good or bad. There is no such place as hell, that is a concept first created by the Greeks, and then continued when Rome finally adopted Christianity under Constantine. Artist along with the Catholic church, and politicians, created some horrific images of what they believed Hell to look like. These images frightened many, and kept them in line with the church which is a huge part of what kept the Catholic church so strong... It was government getting its hands into religion.
However though if you were good, meaning you had love in your heart for Jehovah god (god is just a title not a name), and you did your best (remember only Jehovah knows someone's true heart no man, no matter how holy he claims to be). You will be resurrected, which is the promise, and gift which Jesus (who is not god, but the son) spoke of. When you are resurrected in Jehovah's kingdom (because right now the world belongs to Satan) you will live and be as man was intended to be, before Adam and Eve disobeyed Jehovah which was also pretty much a test between Jehovah and Satan. Satan rose the question "why should man worship you?" Satan believed he was just as beautiful and important if not more than Jehovah god. Jehovah being the fair god that he is, allowed Satan to have contact with Adam and Eve.
The tree and the fruit in the story, are not important. Its the fact that they disobeyed Jehovah after constantly thinking about eating from the tree, after Satan tempted them. This theme of constantly thinking something bad is also in the story of Cain, and Abel, even the Exodus story when Pharaoh Ahmose' wife constantly instigates by calling Pharaoh Ahmose weak, and that he should go after them.. He thought about it and thought about it, then acted on it and well ran into trouble when the waters came crashing in.
The answer to Satan's question to Jehovah when Satan first challenges him, is the way the world has become.. Look at what we've become, what we do to each other, how we've destroyed the Earth. The hate, the suffering and it seems to only become worse.. This is why Satan's way is not the way, this is why Jehovah is god because the suffering of mankind and the destruction of the world hurts him, because he loves us so, and when the time comes he'll put an end to it.
Now about what happens when you're "bad". Being bad doesn't mean not going to church, or not believing in god, or even believing in another god because there are so many out there who haven't gotten a chance to know Jehovah, or had it presented to them the wrong ways, or were hurt by people who claimed to be a Christian but their actions show otherwise. Bad means people who vehemently reject everything the father and the son are about, have hate in their heart wanting to watch the world burn. People who enjoy the suffering of others with absolute no remorse in their hearts, meaning their hearts are without light and impossible to know, and remember again only Jehovah knows a man's true heart.
These people are not resurrected when the time comes, they remain non existent, and will not be missed or mourned.
