You seem to be suggesting that in a contest between infinite mercy and infinite justice, infinite justice wins. Why would that be so?
only if you refuse His infinite mercy given in the form of the sacrificial lamb, Jesus of Nazareth. when people voluntarily reject His mercy, then they voluntarily submit themselves to His justice - based on His terms - not their own. there's really no contest between His mercy and His justice. He leaves it up to each person to choose the basis upon that person will be judged. do you want mercy or justice?
again, this may all be a big myth. Jesus may have been the biggest con man who ever lived or maybe He didn't even really live. but i don't think so.
Jesus came out of the grave and His appearance to a small sect of frightened Jews changed them into a band of brothers who brought down the most powerful empire on earth and changed western civilization forever. to those who receive Him, He makes Himself just as real as He did 2,000 years ago in Jerusalem after He came out of Joseph of Arimathea's tomb that was guarded by Rome's finest. God is the most pro choice character in the universe. He leaves everyone's eternal judgment (as well as most other issues in life) up to them.
