'immoral' is the definition.
(synonyms)
'destroying lace in hut' is the wordplay.
'destroying' is an anagram indicator.
'lace'+'in'+'hut'='laceinhut'
'laceinhut' is an anagram of 'UNETHICAL'.
(Other definitions for unethical that I've seen before include "Morally wrong" , "Dishonourable" , "Unscrupulous in business or professional conduct" , "Not morally correct" , "In breach of business principles" .)
