Lincoln and Syphilis

[Gene C]

Herndon certainly stretched the truth about the character of Thomas Lincoln, Abraham's relationship with Mary, and his severe depression at the death of Ann Rutledge. Some speculate he did it to show the obstacles Lincoln had overcome in his life. Others have mentioned that Herndon felt he new Lincoln better than anyone else, even better than Lincoln knew himself.

So what is the purpose in Herndon relating this story?
That Lincoln was tempted, but overcame the temptation, maybe embarrassed about the whole incident ?
That Lincoln was ultimately an honorable man?
Even as a young man, especially as a state representative, Lincoln was concerned about his image and reputation. Certainly Lincoln knew the consequences of such a relationship. People may have been promiscuous, but it seems to be more frowned upon than it is today. For Lincoln, as a young ambitious attorney, it could be a career killer.

Yes, the incident is possible, but there is something about this whole story that just doesn't seem to fit.
