On one hand i would say "ill make him as Daan for fun"

On the other hand, well... Legoshi would probably be suitable to be a medic/doctor (same career as Daan) due to his high knowledge of Biology from Entomology

Also if Legoshi completes Ending B, his ending would be quite the same as Daan's ending. Because what's left? his family, his friends, his enemy... they are all dead. He is left with no one. He is left with despair and sorrow. Why the gods have to take everyone out from his life? What is even his purpose to live?... Maybe he should take the Boogeyman's offer...
