Religious and evil too, unfortunately (10)
I believe the answer is:
'religious' is the definition.
Both the definition and answer are adjectives. Perhaps there's an association between them I don't understand?
'and evil too unfortunately' is the wordplay.
'unfortunately' is an anagram indicator (a bad or unfortunate spelling).
'andeviltoo' with letters rearranged gives 'DEVOTIONAL'.
Can you help me to learn more?
(Other definitions for devotional that I've seen before include "Of worship" , "Short prayer service" .)
