I dont think they are representative of most of the Thalmor. Think about it.
The ones who are there arent fighting wars. They arent holding territory. Instead, they were shipped off to a cold, hostile place that has little in the way of central government. Your task? To wander the countryside to attack people who worship Talos.
That is IT. That is your life. That is what they do day in and day out. Im guessing they were stationed there due to being rather lame soldiers. Its probably viewed as a punishment.
Ha. Didn't think I'd feel sympathetic for a Thalmor anytime soon. Not only are you in lovely Skyrim,
but everyone hates you. Actually that's not true. I did find one Thalmor sympathetic compared to the others: Ondolemar. (Although to get on his good side you have to be...unscrupulous.) Like all Thalmor, I find him hilariously snobbish and awful, but I like him. He reminds me of the evil rich kid characters in '80's movies. So over the top.
Spoiler He's friendlier after you help him: he can make a distraction for you during the quest Diplomatic Immunity.
Stormcloak questline made me sad though:
Spoiler He's dead when Stormcloaks take over Markarth. Doubt it was natural causes. Obviously suicide. Imagine if you will, the innocent explaination: Stormcloak guard -- "He kept hitting my warhammer with his head. I think the stupid elf dented it."
So not every Thalmor is a
complete jerk either. 99% jerk. Regular Altmer come in all types, thankfully, like Nords vs. Stormcloaks.
