This is just the "bad apples" take, repackaged. You think bad actors are to blame, and that if you weed them out the institution will be cleansed. You miss that the problem is the institution itself and it's very nature, not individual actors. If you reformed the institution to not be this way... Then you'd effectively be doing abolition, the thing you think that you're not looking to do. And it would likely be a much more radical change than you envision it to be.
