No, I believe God has every idea of fairness, and then some, and that He is aware of degrees. However, all you have to do is steal one time to be a theif, murder one time to be a murderer. This isn't just the way God sees it but the way our own law and culture sees it. You sin only once - you are a sinner. Thus, still in need of His salvation.
I did not say that God sees us as nothing - if we were nothing, how could He love us? When my children disobey, they are wrong - does this mean I see them as nothing? Certainly not! Sure I get angry at them, but I still love them very much and would be willing to die for them. I discipline them to teach them right from wrong because I love them and desire what is best for them. If I allowed them to do whatever they wish and gave them no boundaries or discipline - they will learn nothing and most likely be lazy, trying to find a way to live off of government or they will end up in prison (o yeah - that is living off the tax payers money too!).
I love them to much to want to see them end up that way so I teach and discipline them, but I still can not make their choices for them. I give them all I canm but they must choose what road they want to take. God does the same for us - He laid down the laws but we must choose to accept and obey. If we don't, we choose the punishment that He would rather not give us but will because He is just. If we ask forgiveness - then He offers His mercy (not giving us what we deserve) and grace (giving us what we don't deserve).
