My halfling wizard. He’s just a silly little guy with a monkey on his shoulder (which is also his dead brother). Don’t mind that time he dropped a psionic nuke on a hex of the continent map as a distraction. Totally Chaotic Good.
One of my Pathfinder characters, Bentithan Flinteye. He’s an evil, but pragmatic, Aasimar psychic warrior, who considers his actions to be for the “greater good”. He’ll use this to justify a lot of things to himself and others, but make no mistake he’s evil and ultimately just wants more power for himself; after all, wouldn’t he be able to do more good with that power? There would be plenty of people who’d think he’s right.
Mine is an entire faction. No, the rebels aren’t the good guys, the leaders are baddies. Theres just a lot of propaganda and in-universe nice people fall victim to it, including the protag. There is no high ground.
