1) There are numerous circumstances that take place during a presidential administration that have to do with the national debt, very few of which are personally or singlehandedly engineered by the sitting president.
2) The US national debt has never had any instances in which it did not increase. To say that one president is a hero or was a hero because of how the national debt performed (or was handled), and that another president is ow was a monster because of how the national debt performed (or was handled) seems shortsighted and an ill-educated perspective of national and world economics.
