Hell is for sinners in general, and that's all it's ever said to be:
Revelation 21:8
New King James Version (NKJV)
8 But the cowardly, unbelieving,[a] abominable, murderers, sexually immoral, sorcerers, idolaters, and all liars shall have their part in the lake which burns with fire and brimstone, which is the second death.”
You're not thrown in Hell just because you don't believe in Jesus, you go to Hell because you're a sinner - a rebel against God's law. And the only way that your sins are covered is to trust in Jesus alone for salvation. See http://needgod.com
Meaning, most people who claim to be Christians really aren't. That "Christian" who acts and has always acted just like all your friends who aren't religious (sleeps around, lies, whatever)? He's really not one. Christians won't be perfect, but they will genuinely try, and largely succeed, in following the Bible, because they love the One Who saved them from their sins (which is what sends you to Hell).
This has been your Good Theology Moment. If you'd like me to expand on any of the above, just ask.
