except for the fact that the reason why cancerverse beings weren't effected was because they had stopped death on account of the many angled ones and Mar-vel's dickery.... Mordru just never had death in the cards to begin with... So stating that thanos finding a way to stop the cancerverse by letting his ass get beat to death is in no way the same in context as how he would defeat mordru whose inability to die is independent from the lack of death in the universe. BTW Mordru >>> Lord crazypants marvel and his allies. So he still beats thanos' ass into dust anyways.
