Please help me write one paragraph

do you believe General Zaroff is a credible character( credible mean in real life) would this character exist in our world or is the character believable in the world the author has created?

General Zaroff’s refined mannerisms conceal a maniacal desire to inflict suffering and death for his own amusement. In many ways, Zaroff considers himself a god who can snuff out life as he pleases. Zaroffs’s madness stems from a life of wealth, luxury, and militarism, which inflate his ego and sense of entitlement and impose few limits on his desires. Zaroff began hunting at an early age when he shot his father’s prized turkeys and continually sought out bigger game in his family’s tract of wilderness in the Crimea, a peninsula on the Black Sea. Commanding a division of Cossack cavalrymen in Russia, meanwhile, familiarized Zaroff with the horrors and atrocities of warfare. His bloodlust and passion for hunting eventually prompted him to hunt men, the most cunning and challenging prey he could find.
