I actually agree with him to not actively partecipate in the coup, for the reasons already exposed before and becouse IT is a problem when a revolution is ideologically centered around a single person, as the holy queen and the prince wanted.
He could however be involved in a semi-active way, as a hidden overseer tasked to dirige the revolutionaries, without exposing his true identity, acting trough a net of cells, as a way to prevent external powers to gain excessive influence in the movement. Becouse can you trust external powers (in this case referrals of 2 others nations) to have the best interest of the nation they are staging a coup on? Heck you can't be even sure with internal powers.
He doesn't even need to leave the village, it's the perfect base to boot a secret revolutionary governemnt or to use as a base for rebels.
Even if he didn't want, considering how moral he was described, when they mentioned the famine he could have proposed a sort of:
"we have food and fields, but we miss personnel, help us getting them and we will provide foods ease the hunger of the starving masses, if you help us manage the markets."
In this way he wouldn't have partecipated in the revolution, but at the same time he wouldn't ignore the suffering people.
But no, they had to write in this awful way.
