Preston Packard/Samuel Jackson's character...
This wasn't the first movie where he was like this...
[spoiler]Refresher for this one... He wants to take down Kong b/c he attacked and killed his men. Well intentioned, but TBF, Kong thought they were the bad guys. I reckon it's nothing Packard himself wouldn't do.
Plus killing Kong would be at the cost of the bigger picture[/spoiler]
There was another movie where he played that same role. IIRC, at least a 3rd one as well. Has this been his "MO" in recent films?
