Obligation to participate in healthcare for the sake of science
Ebola diagnosed patients face the prospect of a 50% survival rate after a certain period of severe illness that will subject the community with probability of infecting others. The option of suicide assures a certain death that occur before the illness becomes nearly unbearable and at a time when the virus is least likely to infect others. Suicide of course eliminates the opportunity to survive the disease, and like the cancer examples, we have examples of grateful survivors.
