Should that read 'nobleman' rather than 'noblemen', the wordplay being ([E]ARL - L) in (A VICE)? Assuming AVARICE is the solution, I certainly struggle with 'Wish' as the definition, and 'Wish to get' is incomplete, lacking an object, eg 'money'. A little more latitude is allowed in '&lit' definitions, but not as much as would be required here. I'm always sympathetic when the word to be clued is something like 'nayward', which is a horror to define, but here I would have thought that a clue like 'Greed, a sin capturing attention' ([E]AR in (A VICE)) would be perfectly serviceable. Alternatively, the clue as it stands could be modified to read 'Desire to acquire wealth from nobleman left abandoned in absolute depravity'.
I agree about the 'wordplay leads to extra letter' device, something I think should be used very sparingly indeed!
