– Why, oh why do people hate Chaol ?!?!? I. Don't. Get. It.
First of, HE DID NOT call Aelin a monster, he said "Who is to stop the monsters from coming out again? Who is to stop you". That is NOT the same as calling her a monster, he's simply expressing how scared he is of what could happen with all magic-users having their power, and raises the VERY GOOD POINT of Who could stand against Aelin of she goes dark side (which us an understandable concern since last he saw her she gutted Archer, and now she told him how she threatened to burn an entire city of mostly innocents to have 1 person released from an oath). He was raised to fear magic, and all his experiences with it were traumatic, OF COURSE HE'S GONNA BE SCARED.
He cares very deeply about Ardalan and is scared that aelin doesn't (which, let's be honest, she doesn't much), and he's actually concerned for the good people doing bad things because they've been raised to believe it was the right thing (like he was), whereas Aelin kinda seems to consider that nobody good can be there.
Also when she thinks "how could he stand in the same room as the king and not kill him? How could he work for him?". HUM ?!?!?!? Aelin ?!?! You did the same. But you don't even have the excuse having been raised this way.
Honestly both he and Aelin are to blame for their misunderstanding, yes Chaol should've been so vehement, but Aelin should've tried to understand Chaol's POV. They where both just as stubborn as the other and refused to tried another perspective.
But Chaol is definitely not more to blame than Aelin, so WHY DOES SO MANY IN THE FANDOM HAYE HIM ?!?
[– (Edit 22/04) So many people on Booksta are like "Oh, why is he surprised/chocked/disgusted by what Cealena did in CoM ?! What did he thought assasins did ?!"
He is not surprised she kills people, he's was surprised to see her enjoying it and doing such gory things, THAT IS NOT THE SAME. His problem wasn't with the killing, it was with the how.
And again that's a very human and very sane reaction.]

– Chaol say  that Aelin left Endovier "not even a year ago" (p.537), and Dorian'  birthday is on the summer equinox (june 21st). WHAT ?!?!?! Shouldn't it be at least a year ?!?! I thought ToG was like July-December, CoM should be something like February to March, HoF a month later so April, but it takes at least 3 months, most likely 4 (given the walks and travel time and many "a few weeks later"), so that's like already at least July, but now somehow 2 weeks later is QoS, starting 3 days before June 21st ?!?!?! How ?!?!?!
I need the nooks to have a timeline like the Star Wars books have.
