When it comes to RPGs games, I typically tend to play someone who's not me or based on me, but rather someone who is better than me, someone who is inspiring. A hero, so to speak. Due to that, I rarely play evil characters and most of the times it was either in Baldur's Gate (once as bloodthirsty swashblucker by nature, once as calculating sociopath of a mage/priest) or Icewind Dale, where all of my party members are little more than just utility without characteristics on their own.
While I agree that RPGs can and should do better in terms of giving players more options to play evil characters, I must say that playing an evil character isn't limited to dialogue options - you don't need necessary to have your character's evil nature directly, and unsubtly reflected via dialogue options. Think about it, many real-life serial killers were actually quite charming in conversations. Even in Baldur's Gate, the local chaotic evil psychopath Sarevok was extremely popular among Baldur's Gate's nobility.
The other thing is, action speaks louder than words. Let's take, once again, Baldur's Gate as an example. You provoke/are being provoked by a random adventurer's party you meet in the wilderness, or even in populated areas like an inn, the battle ensues and said party is dead. If you had the option to prevent that battle, that is murder. Unlike self-defense, being provoked doesn't justify committing murder. And the game doesn't punish you in reputation loss in those instances - instead, you earn a nice amount of experience points and nice loot, sometimes unique loot. Think of Golden Girdle, which cannot be found any other way in BG1. In the example above you see an option evil party can take. Of course, nothing mechanics-wise can stop the good-aligned party to take that route as well, but in a role-playing game, taking that route shouldn't be something for a good-aligned party to even consider.
Similarly, theft and looting of random houses. Unless caught, you are not being penalized, but the action is still inherently evil.
Based on that I'd say the options are there, just not necessary in form of dialogues etc.
EDIT: Forgot to mention. Asking for compensation for work isn't evil.
