Ehhhh i disagree with this. Not liking the characters because they lash out is more of a taste thing.
Also I feel like youre partially missing the point. Reca didnt even know about the energy affecting his emotions and if she did it wouldnt matter.
Words can hurt people, regardless of if they were meant or not. And hearing your leader who youre supposed to save the world yell they hate you and then proceed to go "it wasnt me get over it guys" aint exactly going to magically fix that.
