why the devil's crossing guards dont help with dread

I saw a post about indifference of devils crossing guards and tried to understand the events from their pov.

You were no one. You were possessed by an aetherial and barely clinging to your consciousness with your teeth. In that too,Sahdinas charms were helping you. The aetherial possessing you left you before you take your final breath on the noose. The mercy of John Bourbon saved you. You had to earn their trusts and show that you are a worthy asset in these dire times. You killed the reanimator haunting lower crossing with zombies. you solved drinking water problem and you destroyed ex warden of prison and the head of the bandits in the west. you helped kids dress and solved food shortage of the settlement. you became the pride of the settlement.

And then... You disappeared without a single word. You forgot the people who gave you, your humanity, honor and everything. Sahdina,who helped you to save your soul, is dead because you did not protect the settlement.

People started murmuring about you, especially the ones you yeeted at riftgates while lying about their safety. You brought shady people to the settlement .The first one was the first blade of the emperor who did nothing for the benefit of the place. He would kill everyone within seconds and no one could resist. You fell for his disguise as a capable cook. One day a homeless guy in ragged clothing appeared at the front gate through a green portal. Yes, another portal to worry about. People remembered how riftgates and portals spew monsters from wightmare and burrwitch incidents. And you followed this shady guy to a safari land with mummies, dinosaurs and other exotic creatures. What is worse, you forgot closing the green rift behind.

They learned about your new adventure. You went skiing at the lands of your former arch enemies. You stirred chaos there and all of a sudden a cosmic dread appears at the heart of the settlement without even using the rifts you left behind. Why should they help you?
