Desire unity, eschewing European lack of morals (10)

'desire unity' is the definition.
The definition and answer can be both human attributes as well as being singular nouns.
Perhaps you can see an association between them that I can't see?

'eschewing european lack of morals' is the wordplay.
I cannot really understand how this works, but
'european' could be 'e' (abbreviation e.g. EU) and 'e' is present in the answer.
'lack' could be 'want' (synonyms) and 'want' is present in the answer.
'of' could be 'o' and 'o' is present in the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
