Does having someone to blame for a deformity make it easy to deal with?

     In Corby, England there are atleast four families that now have children with birth defects and the families believe that a nearby toxic landfill is to blame. This is information from a CNN article called British Families Blame Toxic Stew For Birth Defects. The children are being born with missing fingers. These families all live within a two mile radius of the landfill which has contributed to toxic waste running into a nearby pond. One parent, Joy Shatford, decribes his son's hand as "a palm and five little stubs." This situation reminded me of Quasimodo in Notre Dame de Paris because he also had a deformity. According to Wikipedia, a deformity, dysmorphism, or dysmorphic feature is a major difference in the shape of a body part or organ compared to the average shape of that part. Like these children Quasimodo was different because of his appearance, but unlike them he had no one to blame.
     My question is: Does having someone to blame for a deformity make it easy to deal with? For me the answer would be yes because if I could know what caused the deformity then someone could try prevent it from occuring again. Also, knowing that it wasn't my fault would put my mind to ease. For example, women that smoke or/and drink while pregnant have a chance of harming their child and the child could be born with a deformity. In the case of these four children they have evidence and reasons as to why they have a deformity, which is the landfill.
