Listen, evil is NOT running around killing people. That's being a criminal, or just being an annoying baffoon. Evil is planning to overthrow some kind of government, maybe follow some sort of religion that requires human sacrifices...just something around there. "Waging war on everyone" or "turning everyone evil" is just...stupid! You're not evil, you're just annoying. Please understand, there's a huge difference between being evil, and being a criminal. Criminals aren't evil, they're just greedy. Now, maybe if that person tried to overrule some sort of government, or maybe take control of an area and force the residents to pay him for "protection" or something like that would be considered evil. But I'm seeing so many wannabes it's pathetic. Being evil is making a huge impact on someone, or maybe a group of peoples' lives, and endangering them. Running around killing people and stealing is just you being a criminal, which would fit along gangs or something. That's more of a...neutral-evil? I don't know what it's called, but it's getting annoying seeing everyone want to be evil, and really just killing everyone and taking their cookies.
Evil guilds should maybe have a leader, someone to command a small army, or wait and plan out some sort of attack that will endanger some peoples' lives and actually make an impact on Yliakum - something that the local guards won't be able to stop. Compare this with pickpocketing. Someone steals your purse, they run, the guards kill them or knock them out. The small army, or just mastermind, will probably work around the guards, maybe burn some buildings or something? Then they'll disappear and wait for another attack.
I'm not saying that's evil, but it's more of a step towards becomming evil. The true definition of evil would basically be something huge, not what's going on right now with all the vampires, wannabes, and criminals.
