It seems the most sensible solution to me that the bounty placed on a person's head for griefing another player (or legitimately pirating if they demand loot and the player chooses to fight instead) should be the amount of insurance that player would have to pay to get their ship back.
That way, killing another player in a large ship for no reason would have much more of an impact on the pirate (as it does on the victim).
Sure, you could effectively still "grief" by whamming the guy's hull strength down to 10% so they have a repair bill, but the upside for the victim is that they retain their ship and cargo and while they may be set back by this, they can still get money from the cargo to help pay for the damages, etc.
Seems pretty straightforward really. It doesn't prevent people for killing for no reason, but does balance the cost of doing so equally between the two players.
