Should You Marry Someone From A Very Dysfunctional Family?

You love your spouse-to-be. But their family is something else. Not only are the parents dysfunctional, drug addicts and alcoholics, with violent bursts of temper; the siblings are a mess, in and out of prison for crimes of theft and violence, absent from home so often their children are now wards of the State, raised by foster parents or parceled out to distant relatives. The family is a mess, but should you judge the one you love by the family they come from? Is that being "elitist"? Or is that excercising proper caution? Should you try to interact with your future in-laws or should you avoid them? How can you be sure that your future spouse has not been irreparablyemotionally damaged by their dysfunctional family?
