@Treyon - I don't want to get too political, but people of socialist countries aren't suffering as much as capitalist propaganda portrays it. Even North Korea doesn't look like Mordor anymore.
@Kazedoom - I see this MC as being more human than Ainz. The important differences are, he's thinking with his own head, and he has feelings.
@zuflis11 - the overall tendency seems to be that turning to the dark side gives you an instant boost of power, but reduces your growth, so new generation of heroes will always reach your level. Yet with each iteration, the level of evil overlord would increase, making the heroes' journey harder. Will humanity finally learn to not betray its mightiest heroes, or will it be destroyed first?
