It's difficult for me to express this view, which I hold genuinely, without reading as lacking in humanity. However, I think it would be disastrous for humanity as a whole if we eliminate disease completely. To fight against it and to make progress in that fight is of course deeply human. And we are all affected emotionally and personally by disease of all forms. But if we win the fight against disease, I am almost sure that the human race will just end as a (long term) consequence.
