For example, the symptoms of bird flu include diarrhea, which, like a mole, is only a symptom, not a cause. If only diarrhea is treated, it may be cured, but bird flu still exists.
Symptoms in vitro are symptoms, and so are moles. Mole is a symptom of the disease, and it is the fate displayed in vitro, not the cause, so removing moles can't change the actual fate, and it doesn't matter whether you go or not.
