Why so many atheists, like Moloch, are constantly whining and acting so fearfully? It's like they are scared all the time

On the other hand, it is the hardcore Christians, who are acting fearfully. For example, many of my friends have asked me to convert to Christianity. Their argument is that if I don't accept Jesus as my savior, then I will face the eternal hell-fire after my death. Christianity is a religion which is based on blackmail and fear.
