Torn veils are bad things (5)
I believe the answer is:
evils
'bad things' is the definition.
(I've seen this in another clue)
'torn veils' is the wordplay.
'torn' indicates anagramming the letters.
'veils' with letters rearranged gives 'EVILS'.
'are' is the link.
(Other definitions for evils that I've seen before include "Iniquities" , "Lives (anag.)" , "Sins and depravities" , "immoral actions" , "transgressions" .)
