Get your facts straight! Voldemort was never a Death Eater. The Death Eaters were originally Tom Riddle's (Voldemort) group of "friends" from Hogwarts.

If Lord Voldemort is hanging around your house, the safety of your cheese should really be the least of your worries.

It was too late. Voldemort already knew where the Elder Wand was and was going to get it.

It is a group of people that try to stop Voldemort. We find out about in the fifth book of the series.

It was never about killing somebody, it was about stopping Lord Voldemort from killing more innocent people. Unfortunately, the only way to do that was to kill him.

Harry wanted to stop Voldemort from hurting his friends, family and lots of innocents witches, wizards and muggles. Voldemort started a war, Harry ended it.
