What the hell can we do? They cant just inject HIV and Cancer into a human un tested. That would be murder. If you allow that to happen even if the test subject wanted to die it would mess up alot of the laws on murder. Even if that was aloud to happen it would only be used by people who want to die and the rtesearch would get nowhere and the amount of lives they're trying to save would have to wait. Why dont you quit bitching and offer a suggestion instead?
