The MC is supposed to learn whether humanity deserves extinction, but it was clear from the start that:
a) judging from the classmates, the answer is probably 'yes', and
b) the MC will answer 'no' anyway,
so where's the tension?
The MC's classmates are stuck-up elitists, and the teachers aren't much better. I don't even know why the MC is there, it's the worst place to make this judgement.
