With regard to the Prince himself, it is very certain that, if he had lived, the realms of the Spanish Crown would have numbered one tyrant more. Carlos from his earliest youth, was remarkable for the ferocity of his character. The Emperor Charles was highly pleased with him, then about fourteen years of age, upon their first interview after the abdication. He flattered himself that the lad had inherited his own martial genius together with his name. Carlos took much interest in his grandfather's account of his various battles, but when the flight from Innspruck was narrated, he repeated many times, with much vehemence, that he never would have fled; to which position he adhered, notwithstanding all the arguments of the Emperor, and very much to his amusement. The young Prince was always fond of soldiers, and listened eagerly to discourses of war. He was in the habit also of recording the names of any military persons who, according to custom, frequently made offers of their services to the heir apparent, and of causing them to take a solemn oath to keep their engagements. No other indications of warlike talent, however, have been preserved concerning him. "He was crafty, ambitious, cruel, violent," says the envoy Suriano, "a hater of buffoons, a lover of soldiers." His natural cruelty seems to have been remarkable from his boyhood. After his return from the chase, he was in the habit of cutting the throats of hares and other animals, and of amusing himself with their dying convulsions. He also frequently took pleasure in roasting them alive. He once received a present of a very large snake from some person who seemed to understand how to please this remarkable young prince. After a time, however, the favorite reptile allowed itself to bite its master's finger, whereupon Don Carlos immediately retaliated by biting off its head. He was excessively angry at the suggestion that the prince who was expected to spring from his father's marriage with the English queen, would one day reign over the Netherlands, and swore he would challenge him to mortal combat in order to prevent such an infringement of his rights. His father and grandfather were both highly diverted with this manifestation of spirit, but it was not decreed that the world should witness the execution of these fraternal intentions against the babe which was never to be born.
