The biggest disease today is not leprosy or cancer or tuberculosis, but rather the feeling or being unwanted, uncared for, deserted by everybody. The greatest evil is the lack of love and charity, the terrible indifference towards one's neighbor who lives at the roadside, the victim of exploitation, corruption, poverty, and disease.
It is not possible to speak of the right to choose when a clear moral evil is involved, when what is at stake is the commandment, Do not kill!
