@HopelessDemigod why would a god feel vengeful? That assumes they have stakes to care, which assumes they interact with the material world and need to regulate themselves. Then they are imperfect. Do you want your god to be perfect or care? Also, delusion is consigning yourself to never harm others. That's an impossible, perfect standard. Everyone has an impact that leads to suffering sooner or later. A better goal is to balance impact and effect by understanding suffering.
