If there is a coup, the army would silence the Executive and impose themselves. They sack the legislature but they don’t sack the judiciary because they need it to interpret their Decree and lawyers to write same. That is how important the judicial arm of government is. So, when you undermine that arm of government with this kind of behaviour, you undermine the whole system. If you allow the society to lose faith in the judiciary, it will become a state of where the might is right.
