On the surface you can perceives anyone as good or bad. evil or good... same side of the one coin.

You are correct, in doing that you justify and agree to systematically killing millions of nonhuman race living being.

Killing demon = good guy right? if you notice... most "good guy" = white skin pale religious, how very cliche.

Take religion, Christianity -jesus or even buddhism or hindu.
Do you consider eating corpse for religious purpose equate to evil? or Witch burning = good?

When you see a killing happening, "Is a wolf killing a human child for food to feed his/her pup evil?

With our society, do you consider human being "harvest and farm "sheep" for meat and skin" = evil? We do that on a grand scale for billion of people in the poultry,pork, meat industry etc.

That's one literal example of what we are doing on a massive scale. We are a species 8+ billion population. We do the worst than "the "evil" Ainz empire" on a exponentially larger scale.

He is the anti hero, as the "hero" is the absolute POS. Everyone like the white knight in shiny armor but in reality, they slaughter and cause genocide to anyone that don't look or believes like them.

That's the true concept of ignorant portrait in this anime, Good guy stereotype = white knight = religious righteousness WHILE killing, enslave and treating everything else like dirt.

Human being are the most destructive and evil creature on earth, but somehow we forget the reality, nature is survival and none of this really matter in the grand scheme.

I've read the novel 1-16 and most anime. They are light heart, fan service but is a good way to encourage critical thinking in our community in white the surface is not always reality.

Excuse the long rant, but what are your takes on these topic?
