Deformative Influences

We speak of formative influences; why not also of deformative influences?  Parents and siblings, family and friends, church and school, the rude impacts of nature, the softer ones of language and culture — all contribute to our formation but to our deformation as well.  The learning of a craft is a formation, but as Nietzsche sagely observes, "Every craft makes crooked." If so, every formation is a deformation.
