Evil options and evil endings should probably give you more opportunities to make more money, gain more power, so in-turn make the game easier in some ways. Because in the real world, you have to be evil to gain money and power.

Rather than becoming a criminal in an evil run, maybe you just become a capitalist. /Semi-sarcasm

Tyranny is a small but excellent game in that regard. You already start as a lackey (more like a prosecutor) for a tyrant that takes over the game world but a tiny bit of a peninsula housing a few different but unyielding factions. You read the tyrant's edicts and bring about literal disasters like earthquakes, storms and eruptions at the very start of the game, then you can choose whether to continue in compliance, thwart tyrant's generals to your side and rebel, go anarchy route and impose your own will on both the tyrant's armies and the local factions, etc.

Imo one of the rare and true Fallout 1-2 and cRPG followups in the last decade, with a proper flavor of evil.
