What do you mean by lightsaber wounds to jedi? Yoda and obi wan said that younglings had lightsaber wounds, but not any of the older jedi-padawans, knights, masters, etc. Either way, Vader was not nessecary for order 66. He did not help to destroy the Jedi. Almost all of that was left to the stormtroopers. At the end of ROTS, when padme was on mustafar, other than obi wan and yoda and the soon to be born jedi twins, were there any jedi left? What about at the very end of the film? When were the jedi gone? Luke was not the last of the jedi, and they were not gone when he died. He started a new jedi order after ROTJ.
