O que o Predator viu que o fez poupar esse personagem?

O Predator (Scar, como é chamado em Alien vs Predator) teve câncer nos pulmões de Charles Weyland.

Scar considerou Weyland uma presa indigna. Ele só matou Weyland depois de ser provocado por ele.

He implored the others to leave him behind and prepared to face the pursuing Scar alone, hoping to buy the others time to escape. However, the Predator refrained from killing him when it detected that he was dying of cancer, evidently considering him unworthy prey. Enraged by this turn of events, Weyland attacked Scar using a flamethrower improvised from his medicinal inhaler and a flare, causing the Predator to turn and impale Weyland on its Wristblades, killing him before carelessly throwing his body aside.

Scar era um Yautja. Os Yautja têm um código de honra muito estrito.

Hunting Worthy Game: When hunting, the hunter must be sure that his prey is considered game, and lawful to kill. Sometimes the hunter will equal the odds (not using a Plasmacaster or some other weapon). Worthy game must fill the following criteria: Can defend itself and/or is able to kill the hunter himself, of age (killing children and the elderly is considered the height of bad manners), not linked to other lives (so that removing the prey will not doom another, e.g. pregnant women), and not weakened by diseases.

Weyland teve câncer de pulmão, especificamente carcinoma broncogênico _{^{(aviso, link tem imagens gráficas )}}

O roteiro é bastante contundente. Ele não se abstém de matar Weyland porque seria honrado (da mesma forma que matar uma mulher grávida seria vergonhoso), é porque matá-lo não seria digno de seu tempo. / p>

[Below: Human and Predator face off. Weyland draws himself up to his full height. He's going out with a fight. Weyland swings at Scar. Scar catches the ice axe and crumples it in his fist.]

[PREDATOR VISION: Scar sees Weyland in his distinctive heat signature vision. Like an MRI, the Predator vision scans over Weyland's wrecked body, a body riddled with disease. Like stars in the sky, the tumors are everywhere. The cancer has destroyed Weyland.]

[Scar turns away from Weyland and walks up the stairs. To Scar, he's nothing but a sick animal. Weyland is not worthy of the hunt.]

_{^{AVP Final Production Screenplay}}

A novelização é um pouco mais detalhada.

Four years earlier, Weyland had told Max Stafford that, given forty more years on earth, the scientific research his company funded would enable Weyland Industries to open a branch in a moon base on the Sea of Tranquility. But that was before he’d been diagnosed with advanced bronchogenic carcinoma. Now, because of the cancer that was eating away his lungs, Charles Weyland no longer had forty more years. If he was lucky, he might have forty more days.

The creature turned and stared down at Weyland. As blank eyes on the Predator’s faceplate glowed with crimson fire, the human felt a strange warmth inside his chest. Reaching out, the Predator clutched Weyland’s shoulders, held him fast and examined him from head to toe.
Then, snorting contemptuously, the creature pushed Weyland aside and turned his back on him.
Weyland understood what that meant. Somehow the Predator could sense his frailty and did not regard him as a threat — in fact, Weyland was sure that, to this monster, he was nothing more than a sick, helpless animal!
