It's pretty obvious that he send Esther to a suicide mission because he doesn't like her so, Why the heck is no one like suspicious around him? I mean hearing someone getting an uninformed mission that could have killed them should raise some suspicious flag like "Is this guild a third rate?" "Does this guild not have good information on their mission?" Adventurer are basically mercenary if seeing someone get send to a suicide mission they would probably change guild since IDK this guild literally have bad information and send people of to their death?
