【Toward Inmates】 Treats them brightly and friendly, but strictly as "inmate and guard," so there is no genuine kindness or leniency. If an inmate messes up, he might forgive them once, but never a second time, and will hand out punishment.
【Felon Ward Guard】

【Toward Inmates】 Has zero interest in what happens to them. He'll answer if spoken to but won't interact more than necessary. He ignores them if they try to pick a fight and doesn't care if they mock him. However, he properly punishes those who go too far.

Contrary to his appearance, he is devoted. Good at pampering others. Maintains little personal space. Sadistic.
【Toward Inmates】 Treats them with a flippant, smirking attitude. He doesn't know the meaning of mercy; his treatment of inmates is cold and harsh. He might play with inmates on a whim, but discards them once he's bored. He never shows genuine kindness or sweetness.
