Real pirates often try as hard as possible not to kill people. Crew are usually worth more money alive. If you do kill someone, often you get fined by your captain and have to continue piracy to work off the debt.
So real pirates and music "pirates" share that it's not their goal to kill people. The latter still kill far fewer people, and the former still engage in much more violence.
Sorry, I'm just being horribly pedantic, but I suspect that music pirates kill far more people than real pirates, purely because so many people are technically music pirates, wheras the real pirates are very few in number and are also quite likely to be pirating the latest sea-shanties, so there is a lot of overlap.
Sure, to be more precise... "real pirates are disproportionately more likely to kill people by virtue of being real pirates; the same is not true of music pirates."
