Once again...
They said "I play a Rogue because I don't kill."
A Rogue is not a Rogue because they do not kill. They said "the moment you kill you aren't a Rogue anymore." The term Rogue has nothing to do with killing or not killing so, again, basing your definition of "Rogue" off of killing or not killing is incorrect because the term "Rogue" has nothing to do with killing but rather with morals. A Rogue can kill or not kill as they please and still be a Rogue.
And once again....
you said "A Rogue steals things." The term Rogue has nothing to do with stealing or not stealing so,
again, basing your definition of "Rogue" off stealing or not stealing is incorrect because the term "Rogue" has nothing to do with stealing but rather with... well, I wouldn't say morals exactly, but with a certain scoundrelly approach to life (see? Vague!) A Rogue can steal or not steal as they please and still be a Rogue.
Look, steal, don't steal, kill, don't kill, whatever - while the poster you were responding to may have been unable to base his definition on any dictionary meaning, you're in the same boat. I actually agree with you that a "rogue" can either kill or not kill. What I
don't agree with is the certitude you're attempting to apply to a term that is actually rather vague.
It just didn't warrant the 'rofl' emoticon and attitude, I guess.
But aaaanyway...
I fully endorse jpo's approach to the game. One of my best moments in Skyrim was one of my thief characters, sneaking through a Dwemer ruin somewhere. I didn't intend to make a non-killing character, but I just knew I couldn't deal with all the sphere guardians and other automatons. My only option was to sneak past, using arrows for distractions, until I got through.
Also, extremely lucrative!
