What if he is trying to make her realize that no one can help her other than herself? Maybe when he was being bullied teachers maybe ignored him or just brushed it like they are playing with each other and remember the whole class was into it no one helped him and he knows that that stupid teacher she loves is cheating with her father so if he lets her help suzuki will think the teacher just helped her to get close to her father and she won't trust anyone and she may just be bullied more than now apparently they are jealous of her and he is trying to solve the roots of the problem while teaching that stupid father of her a good lesson. I don't know i don't want to think of him as a bad teacher maybe he is misunderstood too you see that student from his previous school he obviously told him that everyone will forget about him not to encourage him to die quickly but to make him change his mind because they don't deserve to die for them since even if he dies they will forget about him and what they did for him. Maybe his methods are hard to understand but let's have faith on him i really don't want him to be a bad guy（/TДT)/
