I think it's the constant struggle between the light and darkness. Some guardians are out here so long, their mentality changes. This also happens irl when employees become disgruntled with the workplace. Think about it, this game is very similar to a part time job. Some days are good, some days are bad....I bet if you had people list comparisons like that it would make an interesting chat. For ex. Bunjie ninjas are equivalent to Human Resources at a workplace. They fire or ban. They also listen for feedback.
