The military has enough systemic issues with unethical leadership or criminal behavior. The Navy has dozens of flag officers being investigated in the Fat Leonard contracting scandal in Singapore. Multiple officers were prosecuted and scores more may still yet be prosecuted. The Army had a parade of generals who violated the UCMJ with affairs that involved subordinates or compromised national security. The Air Force had a 4-star reduced two ranks for an affair with a subordinate officer. A AF one-star at Joint Base Langley routinely drank himself into a stupor in his office while on duty. In 2013, AF MG Carey went on a drinking binge in Moscow and spent most of the trip with two Russian women most likely Russian intel assets. Carey was the commander of 450 ICBMs. It goes on and on. 

If the cadet can't make the standard today, it's best they're shown the door. Ignoring or enabling unethical behavior today just snowballs into an avalanche later.
