Oryx and Crake

Disease is also presented in Oryx and Crake as a weapon of mass destruction. Crake's widespread distribution of his masked virus results in the death of almost the entire human population. Crake is not the only one to use disease as a weapon. Crake himself accuses pharmaceutical companies of inventing diseases and cures simultaneously in order to maintain a high demand for their services. Although one could consider this use of disease a swindle, it is also a powerful capitalistic weapon.
