Fainting can only be fatal if you have a pre-diagnosed disorder. People with diabetes who faint, can be extremely fatal since this can lead to coma. Fainting can also be fatal only if you hit your head on the way down or are put into danger while unconscious.
That depends on what you mean by lethal. If you mean e.g. the gene for Huntington's disease than this is because the carrier is likely to pass on their genes before death as it only manifests later on in life. Unless the gene causes the carrier to die before they reproduce - it will stay in the gene pool. Would you kill someone because they had a genetic disorder or not let them reproduce?
Yes. Since they can not reproduce and metabolize on their own but require a host to do so they are obligated to be parasitical on living organisms.
If left untreated yes it is fatal
