TL;DR: How do you roleplay as an alliance warlock? How do you deal with being a 'good' warlock?
I began my warlock as a human a long time ago. Most quests back then had me just a random grunt, tackling the shitty jobs (sometimes literally). My warlock was an Arathi, specifically with close ties to Alterac. Before the first war he was an Alchemist with an affinity for the dark arts, but ultimately when the orcs invaded he was quick to use his dark skills to undermine the horde. Though approached by demons later with offers of betraying the human kingdoms, or the alliance, my warlock felt that he was more likely to avoid being given orders if he was his own agent.
Burning Crusade is out and my Warlock is loving it. Time to experiment on demons openly, experiment with nether energy, and void energy, and fel energy. Back then he was getting a lot of attention as a demonologist.
Northrend comes along, and now he's getting nervous. He's literally recruited, and gets to skip the line? Thankfully he's excited to explore the titan machines and finally begins experimenting with technology. He also really wants to help kill Kel'Thuzad for giving Hillsbrad warlocks a bad name.
Cataclysm was a low-point. He was caught in Hillsbrad when the forsaken invaded so he drank the blood of Crowley and was forever transformed. Now on top of being a warlock he's struggling with a violent tendency. During this time he really really dived into destruction magic, and got very good at snapping his fingers to get the attention of his enslaved demon.
Mists of Pandaria comes out and he's recruited again and being given all kinds of pats on the head in Lion's Landing for making a difference in the war. Thankfully he can pop off and loot a few Pandaren relics.
Now here is where I'm struggling: here I am in Draenor again, except now we're really seeing some evil demons doing some evil things. In-game I don't see any warlocks working for the alliance that I can take inspiration from. And not only that, I'm apparently a Commander now, and being put in charge of an entire military base/village. I'm struggling with how I can continue justifying being a warlock if I'm apparently some hot-shot alliance hero. Meanwhile my very class it at the crux of all the evil that is going on around me.
How do other warlocks roleplay their allegiance to the alliance? How do you imagine your character reacting to moments where Paladins and Priests are saluting you? Are there any good warlocks we can look up to?
