If god is real and knows human nature more than anyone, then why would he cast people into hell?
You see, Christianity is flawed. Generally no one loves me before meeting me first, and then, you don't generally love that person so altruistically.
I'll put it this way. If you have a crush on some one you don't know. Then you find out that they don't know you or love you. So you want to through them into an eternal hell? That's psycho, and if you ever meet someone that insane, RUN FOR YOUR LIFE!
Atheism, it equals logic, not a psycho judgmental religious dictatorship based punishing for on thought crime.
