Questions for Theists

A fellow atheist on Youtube named ZOMGitsCriss came up with some really good questions that I think about often, and I would really like to hear what theists have to say to these. Here's the video:



And here is a break down of the questions she asked:

1. Would you be able to enjoy heaven knowing that people you love are tormented in hell?

2. How come so many times the all-knowing God doesn't seem to have a clue on what's gonna happen?

3. How do you justify God punishing Adam and Eve for something they did before having any knowledge about good and evil?

4. What will happen in the Afterlife to the people who never heard about your religion?

5. How do you justify an infinite punishment for a finite crime?

If you have a Youtube account, respond to ZOMGitsCriss. If you don't I want to read your answers and share them with her.
