'cannot be a devotee' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'died unfortunately so' is the wordplay.
'unfortunately' is an anagram indicator (a bad or unfortunate spelling).
'so' becomes 'cant' (I can't explain this - if you can you should give a lot more credence to this answer).
'died' with letters rearranged gives 'dedi'.
'dedi'+'cant'='DEDICANT'
