At the beginning of Solomon Kane (2009), Solomon battles the Devil's reaper who claims the Devil wants to collect his soul because the deal is over. Solomon denies any deal and says he can't have it.
Throughout the movie, there is no mention of Solomon making any kind of deal which leads me to believe there wasn't one made between Solomon and the Devil directly.
At the end when Solomon finds his father, his father says he summoned the sorcerer to heal Solomon's brother after his fall. Then he proceeds to say he begged the sorcerer and offered him "everything" which made me believe that Solomon's father offered his wealth, lands etc, AND Solomon's soul. After all, their relationship was non existent and it was Solomon's fault that the sorcerer needed to be summoned.
So why is it the Devil wants Solomon's soul?
