Maybe destroyer’s love for adult and for every person who loves (10)
I believe the answer is:
worshipper
'person who loves' is the definition.
'worshipper' can be an answer for 'person' (worshipper is a kind of person). I am not sure about the remainder of the definition.
'maybe destroyer's love for adult and for every' is the wordplay.
I cannot quite understand how this works, but
'love' could be 'worship' (worship is a kind of love) and 'worship' is located in the answer.
'every' could be 'per' (I've seen this in other clues) and 'per' is located in the answer.
No letters remain.
This may be the basis of clue (or it may be nonsense).
(Other definitions for worshipper that I've seen before include "Churchgoer" , "person in church?" , "Practiser of religion" , "One adoring a deity" , "I believe" .)
