Scroop is best described as very cruel, murderous, greedy, manipulative, and devious. He is an intimidating and treacherous pirate who was preparing to kill Jim Hawkins when he was eavesdropping. He is also shown to have a minatory and mysterious nature and is quite uncaring, opprobrious, disrespectful, and vituperative towards anyone else, even those he claims to be extremely loyal to. An example of this is when he kills Mr. Arrow despite Silvers explicit disapproval of said action, going as far to smile while the crew mourns this loss.
Scroop is an extremely cunning villain, able to blame the death of Mr Arrow on Jim, and has hinted intentions of staging a mutiny withing the Pirate Crew, challenging Silver when he insists on keeping Amelia, Jim, and Doppler alive. He challenges every order given to him by the Pirates, and only is seen as 'submissive' when his life, or his chance at the treasure, is on the line.
Overall he is an amazing actor, able to fool Mr Arrow in believinging he was remorseful for his fight, trick the crew into believeing Arrows death was an accident, slip his way up Silvers ranks despite obvious tension between them, and nearly able to kill of all of those who stand between him and his treasure. Although to say merely enjoys killing and treasure eliminates any intent behind his actions, although hidden. He doesn't simply enjoy mutiny without cause, as if he did he would not be in a pirates ranks, he enjoys revenge, and if it happens in the ships mutiny it is simply a perk.
To say it best, he enjoys taking what he believes is his to take, be it treasure, a life, or the role of leader.
