“Is infinite punishment the proper response to a finite crime?”
No. And thankfully for me, and you, and everyone else, 'your God' is more merciful than you are.
No human being with enough self-awareness to recognise the he or she is usually mixed parts good and error (i.e., knowing better and doing worse) would celebrate the idea of torture - let alone eternal torture - for anyone or any thing.
No person who has actually seen suffering wishes to multiply it, and to such a ridiculous extent, unless he's a sadist..,Ray.
You should know this verse:
"For I was an hungred, and ye gave me no meat: I was thirsty, and ye gave me no drink..." -- Matthew 25:42 (KJV)
If I were to write you and warn you and you ignored that, your god - my god; the strange and ancient being that for some reason has benevolent feeling towards its oft brutal naked apes - will see it and that you ignored it. Under normal circumstances, in situations like yours, getting warned by something like me and ignoring it would increase your debt...except I can't "hurt" you: You've already been warned, hundreds of times and primarily by other Christians no less!
You're already running on the wrong side of your own line:
Each of us has sinned against Him a multitude of times, the seriousness of which will be seen on Judgment Day.
What you fail to do is as obvious to it as how you act. It knows every if (actually, when) you saw a drunkard in the gutter and left him there - and worse, in your case, is that you justified waving the driver by because that man failed YOUR test.
