Due to Wave's background him switching sides would make no sense it was because of someone who acted as his patron that he was able to enlist in the navy and eventually became a Jaeger he would consider it a betrayal of that person's efforts for him if he became a revolutionary. He also has family and was popular in his village. The prospect that Honest would punish them for his treachery would make him feel guilty and perceive that his decision is selfish. The fact that he would not be able to go home after the revolution is concluded would make him succumb to despair even further. In Chapter 15 he is aware the Empire is corrupt due to Seryu's personality and actions but he believes the debt he owes to his patron is more important and to pay that person back being a soldier is the only means to fulfill that objective.

Run would be a better MC because he is aware of both sides of the issue but witnessing the further atrocies perpetrated by Honest would probably make him ambivalent to his ambition and he would be more inclined to help Night Raid but but not join them until a later point. Run's background ensures he has nothing to lose if he defected.
