Now, in their hearts, Herbert is already the hero who "within just a month, has driven the evil nobles of the Kingdom into a corner, making them struggle at death's door."
Yes, a hero indeed.
Herbert had the paladins spent over half a month in the slums helping the people, just so they could witness firsthand what residents of Frost Crystal Kingdom were going through.
He didn't deliberately tell the paladins what the enemy looked like but gave them an opportunity to witness it themselves.
See what kind of life these people lead, make them believe that all Frost Crystal nobles are evil.
Herbert meant for them to understand—even if I commit genocide against the noble families, my actions are completely righteous.
Everything I do is for the poor people, all for them to have a better life.
Eliminate evil, guard justice.
Acting in righteousness through acts of slaughter.
In the name of justice, execute acts of destruction.
If handled well, the two can be indistinguishable.
