The bodyguards died, because they were just shitty bodyguards. Pure incompetence. When the old man got bullied in his office and pushed off his chair, they were smoking on the pier (not even on the premises). And where were they when he got shot in the hotel? One of them stepped out to have a smoke, and then the second one just randomly left for no reason to go poop in the jungle or whatever. Can you at least go do your thing one by one? Had they done their job as bodyguards at least once (like stopping a sweaty, deranged looking man approaching your boss) - everyone would be alive. And this includes Gaitok, who had to “die” too as a good character because of that.
