That and I imagine animal game characters such as Cybugs are not really programmed to be self-aware and such. Therefore its harder for them to not follow their programming like others, cause following the programming is very important and its even more important when it replaces animal instinct, the soldiers meanwhile we sort of programmed to be more like humans however so its like they have an easier time of becoming self-aware that they are in a game.
