Looking back, dishonest statement about victor does seem wicked (4)
I believe the answer is:
evil
'wicked' is the definition.
(synonyms)
'looking back dishonest statement about victor' is the wordplay.
'looking back' is a reversal indicator.
'dishonest statement' becomes 'lie' (lie is a kind of statement. I am not sure about the 'dishonest' bit.).
'about' is an insertion indicator.
'victor' becomes 'V' (phonetic alphabet: alpha, bravo, charlie etc.).
'lie' going around 'v' is 'live'.
'live' in reverse letter order is 'EVIL'.
'does seem' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for evil that I've seen before include "Harmful; unlucky" , "Great wickedness" , "Profoundly immoral" , "Very wicked or bad" , "Profoundly wicked" .)
