The premise/lesson of this episode was the opposite. Everyone tried to tell Michael she couldn't save everyone and to leave the 6 most maximum security prisoners, but she showed them.
In earlier episodes this season, the President of the Federation tried to tell her she "still had more to learn about leadership" because she doesn't believe in making tactical sacrifices and thinks she can win everything everytime. Federation President tried to quote Needs Of The Many, IIRC, to which, no joke, Michael in offense retorted that she doesnt have anything to learn and can save everyone everytime, and went on to brag about how many times she's saved the galaxy, and that everyone's needs can be met if President White Lady would just "Do Better" like Captain of Color.
