Domain of Evernight
tem: If this action is blocked, all damage done to vampires in the resulting combat is aggravated.
After the card is played, does the blocking minion have the option to decline the block?
No.
Compare with Dawn Operation where backing out is mentioned:
Name: Dawn Operation
Cardtype: Action Modifier
Discipline: Fortitude
[for] If this action is blocked, all damage inflicted to vampires in the resulting combat is aggravated. Any vampire attempting to block may now choose not to block.
[FOR] As above, but vampires attempting to block cannot back out.

No. Nor before. Once you've declared a block attempt, it either resolves successfully or unsuccessfully. You can't back out (unless cardtext allows it).
