There would remain nothing more for the whole world, except to go to its ruin (Rom 3:19). But God, being not only very righteous, but also very merciful, had according to His infinite wisdom, eternally established a way to turn all the evils to His great glory: to the greater manifestation of His infinite goodness (Rom 3:21-25), towards those whom He has chosen eternally so as to be glorified in their salvation (Rom 8:29; 9:23). And, on the other side, He has turned the sin of man to the manifestation of His sovereign power and His wrath, by the just condemnation of the vessels of wrath prepared for destruction (Rom 9:22; Ex. 9: 6).
As St. Augustine well says; "If all were saved, the wages of sin demanded by justice would be hidden. If none were saved, no-one would see what grace bestows."
