What the Bible says about people deserving Hell

I was somewhat bemused to face a half-hearted argument from more than one Christian, recently, on the question of what the Bible says about people deserving Hell.

Rather than go into details in this OP, I’m going to leave specific quotations from the Bible for the comments below… for now, by way of a sort of straw poll, please answer the following questions:

1. Are you a Christian?
2. Does the Bible say that everybody deserves Hell?
3. Does the Bible say that most people will end up in Hell?

Bonus question: Is the Bible written in a clear, concise and straightforward fashion, or is it frequently ambiguous?
