Voldemort didn't kill him, nor did anybody else.
Viktor Krum was a student at Durmstrang.
No. People assume that only because the headmaster of his school happened to be a Death Eater. Viktor Krum was just a student there. He also took no side in the war since it didn't really effect his country, he was however against Lord Voldemort.
Viktor eventually found love with a woman from his native Bulgaria.
Gregorovitch made Krum's wand.

The headmaster of Viktor Krums school Durmstrang is Igor Karkaroff. It is believed that Durmstrang is in either Bulgaria or Norway. Igor Karkaroff was a Death Eater, but in the fourth book/film, he flees from Voldemort and presumably goes into hiding. In the Half Blood Prince, Lupin says that he was found dead with a dark mark hanging over him, which indicates that he was killed by either Voldemort or other Death Eaters. We are not told who became Headmaster after Karkaroff. In the film Karkaroff is played by Predrag Bjelac.
