People turn to piracy for one reason or another. It may be due to the lack of goods, notably necessities, in the home country of these pirates, which is not surprising, since most of them hail from developing nations.
It may start out that way, but I highly doubt that any human could resist the temptations. Piracy is very lucrative. They don't just steal cargo and the personal belongings of the crew. Some organizations, I guess that's one thing you could call them, will go so far as to have forged documents for the ship made and have small crews repaint the ship while the others secure control so after they're done taking what they want they can sell the whole ship.
However, I am under the impression that pirates are less likely to kill their hostages, allowing them to go free after a period of time. Although the hostages will suffer from the loss of material possessions, they do get to keep their lives.
You're right about them not taking lives, but its a part of their system. Its obvious that crew members make good bargaining chips and could possibly be advantageous if the pirates are looking for a diversion when they need to get away. In cases where they can operate without anyone noticing, human trafficking provides an additional opportunity for profit. If they can make ships just disappear, what's stopping them from doing the same for the crew. I really haven't done much research into the whole piracy thing, but considering the depravity of human society it seems completely rational that pirates would take advantage of whatever opportunity the situation provides.
I think that its safe to assume that pirates, considering the very nature of what they do, are ready to do whatever they have to. Taking lives might not be a priority, but with any kind of criminal, you have to expect that if something will prove advantageous, they'll do it.
