I think that idea is despicable as long as the opposite is true...that the kindly old Buddhist, for example, who literally never hurt a fly and strove daily to be the best person he could be, ends up damned for eternity simply because he felt that his path made more sense to him than the Christian one.
And what, even, of the self-identifying "Christians" who were raised with a vague idea of Biblegod, and go to church at Christmas & Easter, without really giving much thought to religion beyond checking off the right box when filling out forms. I'd say that most people I have met throughout my life were Christian, but only a fairly small percentage were really INTO it. Most seem to be Deists who choose to pay homage to the idea of God they are most familiar with, but will admit that they think there are many valid paths. Would you say that these people are saved? They are certainly not "born again"...Would you say it makes sense to imagine them in hell?
As long as I can look around me and see good and deserving people who do not fit the description of "saved" as per the Bible, and imagine that God would see fit to damn them, I cannot get excited about the handful who somehow get the message--including rapists, murderers and so forth--being "wiped clean of sin".
