Any being who states a desire of NOT wanting to be healed, is in a form of denial (obviously, they need to be healed). Every living being, at the core of it's essence, is ultimately love, and any living being who is not in resonant connection with that love, is in a process of yearning to discover it, no matter how twisted their methods may be.
Anything is possible.
We each have an individual role. What's yours?
Pathogens are a part of the life cycle, as is death. Ultimately, there is no death. There is only change. Death breeds renewal, so really, what is there ever to destroy?
