Hi, I have a few problems with crime management in Skyrim. I appreciate so much that you can be wanted in a place and not in an other, but there are still some odds.

In Solitude I really could not witness the execution of the storm cloak doing nothing, so I had some trouble with the guards. Now I'm wanted and when I have to talk with Delphine near the stables she keeps attacking me. That's ridicoulous, how can I make her friendly? Clearly I don't want to give any money to the imperials, they tried to kill me in Helgen.

Other thing, does anybody else beside me think that essential NPCs in Skyrim are the worst thing ever seen in a RPG?
There were a million better ways to manage this thing. The obvious solution was clearly to avoid putting in the game any essential character: when you kill a NPC you automatically fail any related quest. Other good solutions were to make the essential NPCs fleeing, or to let them stay on the ground for a few ingame hours.
Essential NPCs that simply keep standing up and attacking you non-stop make the game unplayable and ridicolous. In Solitude I have to go for shopping with Jaree-Ra constantly hitting me, and it's so painful to see such a thing in an otherwise amazing game like Skyrim.

Have you tried hiding in a dark corner until the cursor says hidden? That may reset some NPC's hostility towards you

Thanks man, the problem is that Delphine attacks me because she's in Solitude and I'm wanted in Solitude, so I think there's nothing to reset. I've also tried spells like pacify but Delphine seems to be too powerful (???) for them. I think I could solve the problem by console, but I'm wondering if there is a in-game solution.
