What was Andrew Jackson personality as a man?

Andrew Jackson's most obvious personality trait in my mind
was his ferocious dedication to defending what he saw as his honor.  Jackson is famous
for his involvement in a number of duels and is also famous for the degree to which he
became enraged at the treatment of his wife.

Jackson fought
many duels and did so rather violently.  For example, there was a duel where Jackson was
fighting (with pistols) a man who was a much better shot than he.  When the signal was
given to fire, Jackson did not.  He let the man shoot him.  Jackson was badly hurt, but
took careful aim (he didn't shoot at first because he was not good at shooting
accurately and quickly) and killed the man.  This was against the code of duelling, but
Jackson did not care.  This was one of many instances of him being personally involved
in violence touching on his honor.

Jackson was also famous
for his devotion to his wife and his fierce defense of her.  They married when she was
still legally married to her first husband (neither of them knew she was still legally
married).  Because of this, she was heavily criticized, especially during the
presidential campaign.  She was accused of being an immoral adulteress, basically. 
Jackson was always very quick to defend her, sometimes
violently.

Jackson's most prominent personality trait to
me, then, was this inclination to defend his honor, even to the point of extreme
violence.
