Honestly this is definitely one of the better reincarnated as the villain stories, most of the time they just become the unironic hero but this time he still commits the violence that turns people against him and it is understandable that a noble house that's involved in grey zone operations would be treated with suspicion and thought of negatively, the different parts of the story fit together well without taking away the main reason I would want to see a story about someone being reincarnated as a villain.
