It is not God's justice that is in question, it is the belief that one can really get away with doing wrong and that religion is the trick that does it. The Bible does not teach this, but most versions of Christianity do.
If Bible conversion is correctly understood, it is anything but "free." It cost the incarnate God His life and it costs the convert everything. Anything but total surrender is not regeneration. "Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new. (2Co 5:17)
Most Christians believe salvation is something added on to their lives. Most even talk about, "two natures," the old unsaved nature and the new regenerated nature. If the old nature is not irradicated and replaced with a new nature, it is not conversion, but a superstitious belief in the magic fee ticket to heaven.
One might sin all their life and then enter into a relationship with Him on His grounds, but that doesn't mean one's rewards will be as great as those who remained obedient and bore fruit throughout their lives.
On what grounds does one who, "might sin all their life," receive any, "reward," at all? What are they being rewarded for?

My statement is easily misunderstood. Obviously we are rewarded for good works after salvation. The point made is that if one gambles to remain unrepentant for most of their life before the first death, and only repent later in life, they afforded less time to remian obedient and failed to take advantage of past lost opportunites to work within His will.
Since we have volition, we can compare how a possible world may have arisen had we remianed obedient to Him rather than fallen away. The former is always preferable. Sa;vation is independent of our good works, but our rewards in heaven will be based upon our evidence and good work. Thank You Lord.
