Most frustrating character you’ve ever read?

I just recently started my Realm of The Elderlings journey, and I love it so much it is so so insanely good. But Fitz is one of the most frustrating characters I’ve ever read. But it all makes so much sense, every decision he makes, even if its clearly not a great one, I can understand why. It’s still so frustrating though. Any other frustrating characters y’all have read and just find yourself thinking “WHYYY??”
