Well even tho Poe was a confirmed Episcopalian, that confirmation process usually ends around the end of middle school...he seemed to then back off that commitment starting during his teen years.
By age 27, I'd say what sums up his lack of morals could be found in that he married his 13-year-old cousin at this age!
Unfortunately, there are "bookends" people -- tho "spiritual" at the beginnings -- and end-- of life...
Marrying a cousin was the norm for the vast bulk of human history; the little villages that were home to most humans offered few other options. Bar Mitzvas are held around the thirteenth birthday because that was the low end of the marrying age, again for most of human history.
The facts of Poe’s marriage are hardly evidence of immorality given the time. It may have been a stain on the reputation of Jerry Lee Lewis to do so but I doubt it was much news in Poe’s day.
At least he married her!
