Hell-fire-ists: is it fair for god to give you a better chance than he gives me?

You already concede that you don't deserve the gift of grace that god has given you. So you admit that it wasn't your humility or any attribute of yours that prompted god to give it. You can't tell me that it's because my "heart isn't right", cos you've already admitted that your "heart's rightness" wasn't what made god act. So how can you criticize me, and more importantly, why would god punish me WITH ETERNAL AGONY, for not having a thing that he hasn't given me?
