A lot of people who leave the US army never really do anything to atone for their time in it or they continue to support structures that empower the military. In these discussions, it's always a divide between people who want actual rehabilitation and restitution for the affected populations vs. people (typically from groups unaffected by the military) for whom "they feel bad and said they're sorry" is good enough to earn their forgiveness and elevate them to positions of power.

The former was Aaron Bushnell, who at least based on his final action, we can assume would have worked to dismantle the military industrial complex. The latter was the Graham Platner situation, as he was someone who still showed support for the military overall and advocated for positions that would necessitate the use of the military to exploit other nations.
