Can't sympathize with the protagonist at all. If he had just killed them and then left he would have retained some points, but his suicide at the end was just pathetic. If he was just going to kill himself why murder everyone else as well. No matter how cruel the girls had been, his ultimate decision to die himself just made him seem a retard. At that, the girls never truly seemed all the deserving of being murdered. The school and system itself was corrupt so the protagonist should instead have gone after the ones that had created the school.
Likewise the only girl that looked even remotely different from the other girls was Kululu. Didn't feel there was a point in having so many girls die when they all looked the same. I mean maybe if they had all been clones but that wasn't the case here.
