The missing word in that puzzle is vengeance.
Thank you! Oh my gosh, I'm SO silly, that was the first word I thought of and I googled that word to check the spelling and misspelled it and didn't notice that google corrected me, assumed mine was the right spelling and therefore couldn't possibly be the answer because it was a full letter short. No joke I was sitting here like, okay must be a made up word I'll try different combos. Thank you. SO silly, I knew it must be a me problem.
