I would say it would most likely be the result of a less than ideal cultural upbringing. Even if this is the case, it does not necessarily mean that someone who comes from a home environment that promotes poor decision making that they are not decent people, merely that their senses have not been properly trained.
Now for an adult who has been tatooed and is married, then I suppose that he can always use the signs of his prior life where poor decision making played a key part in this daily life as a living contrast to his new life in Christ; much the same as someone who has had a criminal past can do - where it often can be turned into a luctrative story within many church circles.
Of course, for the teenager and particularly for the younger teenage girl who has marked her body, then she may have to wear this badge of shame for many years where many a fine potential husband might be inclined to keep his distance. For the life of me, I cannot fathom for a second why any Christian would encourage a young Christian girl to deface her body; I am of the strong opinion that if a church discovers that one of their members has unduly encouraged a young girl to do this then the errant adult should be advised to leave the congregation.
