Oh god..what wicked thing hasn't Miss Mordrake done? That's the question you should be asking. Her laundry list includes manipulation and constant lying, betraying family/friends to advance herself, abuse of the environment and natural resources, exploiting the global poor to build her foul (magi)technology, murder...the list goes on and on.
Out of all of them, though, her greatest crime would likely be the wholesale conquest and destruction of entire worlds via (magi)tech that replaces their current reality with a new one she can control like one big live action version of the sims. You see, she extracts those world's souls which she then uses for energy, which of course would normally kill all life on that world. However, instead of letting that happen she proceeds to keep the sentient life alive unnaturally as prisoners in the constructed reality created by her (magi)tech. Oh, and to make matters worse she passes off these seized worlds as part of the setting for a "MMORPG" that people can play, with the enslaved and totally controlled citizenry passed off as the NPCs or worse, enemies that are killed and then resurrected only so they can be "re-spawned" and slayed again.
Yes, I like villain protagonists, and don't worry, despite all of her nastiness, she has plenty of sympathetic points, too....It's just they are packaged along with a totally diabolic side.
If a socialist/Marxist revolution(or if they are in a fantasy/SF setting without the ideas Marx, socialism and capitalism an equivalent type of people's revolution) happened in the MC's country would they stand with the socialist/Marxist rebels or with the capitalists?
