The humans' acts of violence are growing ever more savage.
Not to mention... Doing things themselves isn't the only method humans know.
I heard that even when caught red-handed, they'll lie through their teeth and try to spin it as self-defense.
Byakuren, they're using your ideals as a shield to force even the mighty to yield before their pathetic selves.
I bet they're having a great time. They don't even care about the scorn of the people around them.
People drunk on borrowed power tend to forget their true standing.
