“bi-han is the better sub-zero” “kuai liang is the better sub-zero” you are missing the point bozo
kuai liang is the better sub-zero because he is able to make the lin kuei better. kuai liang has opportunities that allow him to change his destiny from a lin kuei follower into someone who can reform the lin kuei and change the name “sub-zero” from a masked assassin-for-hire into a teacher capable of and believer of redemption. bi-han cannot be the better sub-zero because he is not allowed to be a better version of himself. he stays loyal to the lin kuei and he and sub-zero die loyal to the lin kuei.
kuai liang’s sub-zero exists as what bi-han’s sub-zero could never be. kuai liang was able to find freedom and bi-han could not. one lives as sub-zero and the other died as sub-zero.
