Death note final conclusions

Answer 1

Basically, when Light Yagami is killed by Ryuuku, we learn that he won't go to heaven or hell. In the manga, it shows a flashback with Light and Ryuuku, when Ryuuku first tells Light this, Light says "There isn't a heaven or hell, is there?" It is revealed that no matter what you have done you will not go to heaven or hell. You will turn into nothingness, 'Mu' is what they called it, think of it as an atheists point of view. We can also conclude that Misa Amane commited suicide, I believe the author of the manga even confirmed that. We learn later that Near takes on the roll of L, and that neither Light or L's death are released to the public, nor was the facts about the Death Note. When Ryuuku reveals to Near that the rule about the Death Note being destroyed was fake, Near then burns the book. In the manga, Mikami dies in jail, after going crazy. Matsuda seems to suspect that it might be Nears doing.
