This puzzles references the previous six 'Cardinal Sins' puzzles (referred to as #1 through #6). You can try to solve this without solving them first, but it might be tricky!
Thanks to everyone who solved (any of) these crosswords over the past week! It grew from a silly pun into a self-challenge, culminating in my first ever 15x15. I hope y'all had some sinful fun.
As a final challenge, if you associate each theme clue in this crossword to one of the septet, the missing item will summarise my feelings towards this whole endeavour.
