I'm a little stuck... Click here to teach me more about this clue!

'deliberate the return of revolutionary spirit it's a crime' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'deliberate the return of revolutionary spirit it's a crime' is the wordplay.
I cannot really see how this works, but
'deliberate' could be 'wilful' ('wilful' can be a synonym of 'deliberate') and 'wilful' is found in the answer.
'crime' could be 'murder' (I have seen 'Serious crime ' mean 'murder' so perhaps 'crime' could also mean 'murder') and 'murder' is found within the answer.
No letters remain.
This may be the basis of clue (or it may be nonsense).

Can you help me to learn more?
