You are so violent and destructive. Piracy is probably the only "business opportunity" that exists in their area. They have no other way of bringing in some money. What would you have done? Let your family starve to death? There is a VERY unfair distribution of income in the world. The pirates should be put in prison that's all.
If there was investment in the area and/or the possibility for these people to support themselves as farmers or workers, then the problem would disappear. The piracy is a sign of the incredible unfairness of the world.
The solution to the underlying problem is NOT to kill those who engage in piracy.
