Simon had learned more from Marek's speech than he expected.
The Commander had not revealed every secret behind the war, and some of his conclusions were most likely incomplete. Even so, he had shown Simon a side of the conflict he had never bothered to understand during his first life.
Back then, Simon had been obsessed with destroying the Demon Realm.
Demons invaded Earth, slaughtered humans, ruined cities, and transformed everything they occupied. They also killed his family and friends before he became a Demon Slayer. To Simon, that had been more than enough reason to kill them.
He never once wondered what demons believed they were gaining beyond territory, slaves, and resources.
He did not ask why the Demon Lords and the leaders of the clans in his past life continued investing armies into invasions that often ended in failure because of him and his past companions. He did not care why weak tribes willingly sent their young through rifts where most of them would die.
