A helpful idea might be to revisit this situation later, after the emotional impact has subsided, and try to construct rational reasons why one should believe roleplaying a pirate in Entropia is morally impermissible, or that the opportunity to do so should not exist in Entropia, or whatever conclusion(s) you actually believe. Try to imagine convincing someone who doesn't already believe your conclusion. They may have as much financial incentive to resist changing their belief as you do, but assume they're acting in sufficiently good faith so as not to maintain their belief regardless of what arguments are presented.
Either you will find good reasons, or you will not. If you do, share them. The reasons, or even the discourse surrounding them, could be of real benefit to the community. I don't have significant financial incentives in either direction, but I have been asking for good reasons to join the anti-pirate crusade for years and haven't found any. In this thread for instance, you've called space PVP useless, but presumably the other party in this encounter got some fun/profit out of it, which clearly counts as useful unless you can articulate some reason to believe their utility doesn't count. You've called the person a thief and a burglar, but clearly they're only roleplaying a thief/burglar in an MMORPG, and moral duties generally aren't invariant across fictional representation boundaries (a killing IRL does not have the same moral status as roleplaying a killing in a video game, acting out a killing in a movie, etc.). You've said this encounter resulted in your having less time to shoot, but clearly maximizing player shooting time at the expense of all other activities in the universe is not a sound game design ideal, else we could do much better by eliminating reload, geography, malls, etc., and just pressing F in a Command Prompt. Finally, you've somehow managed to blame the other party for your cursing them out (or in #calytrade, willing the other party's physical harm/death). To an outsider/newcomer, this type of reasoning probably makes the anti-pirate movement appear absolutely off-the-rocker insane.
If you do not find any compelling reasons, then perhaps you will gain some valuable insight into how multiple people can reasonably disagree on the conclusions you've drawn, and your perspective might shift from "pirates are evil" to "I don't really like pirating, but I can see why some good faith actors might partake in pirating without necessarily disregarding any obvious moral truths." That could also be of real benefit, because you would be able to reflect upon similar situations without suffering the karma concerns you've described.
