Considered scoundrel comedian at heart (5)
I believe the answer is:
rated
'considered' is the definition.
(I've seen this in another clue)
'scoundrel comedian at heart' is the wordplay.
'scoundrel' becomes 'rat' (I've seen this in other clues).
'at heart' indicates the central letters.
The central letters of 'comedian' are 'ed'.
'rat'+'ed'='RATED'
(Other definitions for rated that I've seen before include "Censured" , "Scolded, estimated" , "Reckoned" , "Admired" , "highly regarded" .)
