you were not a doofus for having made the mistakes in the first place. that's all part of the learning and practice processes.
you'd have been a doofus if you had settled for the icky results instead of undoing and trying again.
you are not, not, not a doofus for having undone the quilting you were unhappy with.
and it's important to note that you have grown enough as a quilter to recognize the fact that things were not as they should be. that's a pretty big deal and something to be proud of, too.
