I totally think it's absolutely fine for the Fleur lady to have plotted a scheme like that, and no one should have blamed her. But where her reputation would've gone down would be people should've started to see her in a different light, and that just maybe, the duchess was seeing something that they weren't , in her. The prince can't exactly be mad at her for trying to kill the duchess, but he should've had those rose covered tinted glasses removed, and start realizing that yh, this lady is quite the same breed as the duchess.
