I really don't know what the writers are going to do going forward. While every side having realistic motivations and not being mustache twirling villains is better writing, it creates a problem when your hero just goes around committing mass murder.

Tempering was a useful excuse for the wholesale butchering of large groups of sentient beings, but they got rid of that excuse for reasons unknown.

I would say they could just add soulless robots for us to kill but even soulless robots are being written as loveable good guys now.

Even the void demons of figurative hell have been shown as being redeemable and not completely evil.
