Neither the Vorta or Jem'Hadar could kill a Founder, nevertheless injure him/her. So why not get Odo to hide out behind enemy lines, and kill as many Vorta/Jem'Hadar as possible? The Cardassians obviously had no supreme loyalty to the Founders, but as vassals of the Dominion had to do as the Founders stated.
The Founders obviously had no qualms about killing all of the Cardassians when the need arose, and perhaps may have eradicated the entire species if the Female Changeling had not surrendered.
