Luckily almost all the major xeno and chaos empires also suck majorly and are evil machines. The only major redeemable ones are Tau, who are lawful good (also based, prob better than modern humanity irl) & Orcs who are chaotic neutral and just vibing. Everyone else is evil evil evil.
Torture elves. God enslaving undead machines. Universe consuming biomass swarms. Filth demons. Chaos Demons. War demons. Sex demons are less cool than they sound. Imperium men but possessed by demons and even more evil than before somehow.
