Ending Explained: "When Evil Lurks

💡 What does the ending really mean?

In the climax, brothers Pedro and Jimmy fail to destroy the primordial Rotten by burning it in an abandoned factory. The infection spreads uncontrollably: Jimmy becomes possessed and forces Pedro to shoot him. Broken, Pedro returns home to find his young son already infected, staring at him with pitch-black eyes. Without a word, Pedro executes the boy with a gunshot to the head. The ending is a total, merciless triumph of evil. There is no exorcism, no containment, no redemption—only contagion. The demon is a moral virus that eradicates even paternal instinct, forcing humanity into self-annihilation. Hope dies with the child, leaving a world where the only sane response to infection is species suicide.
