As I understand it, it is believed this shark is a large Bull Shark, known throughout the world as one of the most aggressive and deadly and having the highest kill rate of humans of any species-way more than the Great White.
They are primarily shallow water hunters, having poor eyesight but highly reactive to motion and aggressively and brutally attack anything that interests them. Most fishermen know they have nasty personalities in general and fear nothing-they attack and tear-to-pieces their targets.
The second attack victim in this case was literally torn to pieces in a sudden, unprovoked daylight attack in shallow beach water on his honeymoon-right in front of his new bride.
After two brutal, unprovoked attacks in the same area in a short span of time, it is completely reasonable that the authorities consider this particular shark a supremely dangerous animal, willing to hunt and kill humans as prey without hesitation and it should be classified as a rogue
to be hunted and killed at the first opportunity. The local ecosystem will
not miss this fish one bit-and people will stop dying when it dies.
When one shark's value is viewed as being as important as the lives of two or more human beings..the argument for "it's not the animal's fault.." fades quickly.
