The whole games seems hell bent on ruining the Shatter-Shields.
You have them pay the Argonian workers a fair wage.
They got robbed
Their first daughter was killed by Calixto
You close their monopoly on the Windhelm Docks.
You kill the second daughter (or have the option to) which results in the mother's suicide.
It's like they're the butt of a bad joke that never ends
What makes me feel bad overtime isn't killing, it's that the amount of aggressive people in this game is overwhelming. Every bandit will give his life to massacre you with two handed axes even if he has no chance of winning.
So many NPCs treat you like a low dog and openly insult you, and the problem is you're rarely given the chance to properly retaliate. If you go for punching they'll draw their weapons and you're forced to fight them to death.
I only feel bad when the things I fight are so under-powered compared to me... Or if they are human and still insist on attacking me after I try to spare them.
"Mercy please!" *gets up and attacks you again*
And bandits give you like... 3 seconds to get away before they attack, I can't even strike a deal with them on my evil guys.
I can't say I ever really feel bad killing people in Skyrim. In fact, killing Serana would be a thrill... like when I killed Belethor. It was so liberating! Man do I hate that guy.
Half the reason I play games like Skyrim is so that I can do things in a game that I could never (and would never) do in real life... everything from riding a horse and swinging a sword to slaying villagers who annoy me. Now, I just have to slay Nazeem and I will feel much better.
Compared to the shit i've done in FNV, Im a saint in Skyrim. I totally didint'tstrip Benny and cut off his arms and legs with a ripper....
Im just bad at playing evil characters really, I cant bring myself to be bad....
But I never feel bad. Except maybe the nuke in Fallout 3.....
