I am not going down your indefinite question chain. Jump to the end.
When people murder, attack innocents, we rightfully for survival reasons for example, hate them, am I wrong? So the sense of justice, of hate towards evil and love towards good, is part of our biological mechanism per you or am I wrong?
The way I see it, is God entrusted us his qualities and some of them we know and some of them we don't, but they are all entrusted to us for our sake.
Anger has a proper place, and is a manifestation of moral emotion you may call it, but when applied to evil. Every quality has a proper place.
The way I see it since I do believe in God, and believe the mapping is not us creating God in our image, but that God created us in his image, is that wrath has a proper place in God too.
It's scary when we think of his oneness in ultimate form, is each and every title in ultimate form, which includes Anger. It's scary because it means there is ultimate consequences to our actions and that God is the MOST severe in justice and place of Anger and retribution.
Everything has a proper place. It's better while we have time and the world perishes, to side with the oppressed and not side with the oppressors. It's better we side with truthful in battle between truth and falsehood, and not take side of misguiding forces.
