From a devil's advocate point of view, what you expected out of the player is no more "good RP" than what he did. As players, we often expect a certain level of sportsmanship out of everyone else, but consider:

Your enemy walks up to you. Either A) you are standing there drooling on yourself like a handicapped kid, or B) the gods are protecting you. From a purely objective, IC standpoint, the character should have no reservations killing you if it can.

Does it suck? Yep. Is the player a douche? Absolutely. Is it awful role-play? Eh, probably not (IMHO).

Just remember that CF is a relatively tiny universe. Give your CF time to a game like WoW, for example, and you're going to encounter just as many douche bags, if not more. Assholes and computer trouble are just part of the game.

I used to play Diablo 2 a LOT. Specifically, I enjoyed playing hardcore classic mode, which meant I didn't use the expansion pack and if my character died once, I lost it forever. I probably lost hundreds of hours of play because my computer hiccuped a few seconds before I walked into a cursed demon or because some asshole used a hack or dirty trick to get my killed. Thinking back on that makes me view CF as pretty forgiving and it's players as pretty alright, for the most part.
