I love regret arcs/regret chapter(s), it’s my guilty pleasure.  Some of these are good regret arcs, some SUCK, wish I could label which. But reading the reviews usually give you a good idea.  but they meet the minimum requirement of a character realizing they f’ed up. 
Btw spoilers in this list. Maybe about 2 to 3 manwhas haven’t actually haven’t gotten to their regret arcs yet. I try to keep the new ones to the bottom of the list. But I included them as I’m aware they’ll happen due to raws or novel spoilers.
