There's a fine line between madness and evil.

Personally, no, I wouldn't and won't. I mean, I might talk to the person first, and if it happens to be a complete [censored] and a certain race my character is not fond of, I might just give him a beating, or worse. Eventually, but I doubt it.
I think a real fight would be a more entertaining "first kill experience" than praying on the weak(assuming it's not a guard...).

People act if its against like their morals or something lol on a fantasy RPG. Murder is the name of the game. Im gonna kill the first person I get alone and make sure I also kill whoever is responsible from releasing me from prison. It was a bad decision on their part.

I only kill non-hostile NPCs when I have to, which is basically never.

Kill, yes. Murder, No. There's a difference between killing and murdering, and it's likely that I won't be joining the dark brotherhood (or it's equivalent) on my first playthrough.

Samruai try to solve problems without vilolence. But I'm not a samuria, am I? But no I don't kill no one for looking at me weird. ONLY if they steal somthing from me, cuss at me, or attack me. Or insault me. Because I am Dovakiin, and therefor I DON'T have to take crap from anybody. No even the Nine themselves!

im going to do that fore sure because that what i have done with every TES ive played for the first time
