Steve Rogers is responsible for trillions of deaths

The last son of Krypton solicits a passionate kiss from Lois Lane almost immediately after the conclusion of the battle of Metropolis. The implication being that he was sexually aroused by the occurrence of the mass deaths he helped to perpetuate. Allegedly, there is a scientific basis for this phenomenon. In some tribes in New Guinea, it is normal for a Widow to have group sex openly at the funeral of her husband. Perhaps Kal was disoriented after the battle and simply forgot which continent he was on.
