Tarkin admires Darth Vader's skill

Tarkin found himself actually warming to Vader, especially after what had happened in the Sugi's headquarters. No sooner had word arrived that Sergeant Crest and his stormtroopers were in possession of the Parsec Predator and the codes necessary to launch her than Vader exacted his revenge on the crime lord for having been kept waiting. Tarkin knew merely by the gasping sounds that began to erupt from the Sugi that Vader was performing that thumb-and-forefinger dark magic of his to crush the crime lord's windpipe. By then, too, the ambassador's stormtroopers had rushed into the headquarters, unleashing flash grenades and blaster bolts that had caught the Sugi's underlings by surprise. At one point Vader had asked them whether they actually wanted to die for their leader, and it was when they replied with weapons that Vader drew his crimson-bladed lightsaber from beneath his cape. Tarkin had witnessed numerous Jedi wield lightsabers during the Clone Wars, but he had never seen anyone put an energy blade to such determined purpose or achieve such rapid and lethal results. Two stormtroopers had died in the exchange, but all the Sugi had paid with their lives; Vader's blade had even reduced the repurposed battle droids to useless parts.
