Voldemort asked him to do so.
No, Severus Snape did.
Severus Snape or Draco Malfoy
Sixteen.
Yes! ---------- How did he? What were his attempts to do so??
Albus Dumbledore was killed by Severus Snape. Although Dumbledore, who was dying anyway, had already arranged for Snape to kill him so that Draco Malfoy wouldn't have to and so that the Elder wand would not change masters. However, as Draco disarmed Dumbledore shortly before his death that part of the plan did not work.
Yes. Dumbledore told Snape to kill him if Draco Malfoy was not able to so his death would be short and painless.
draco malfoy, thats when he tried to curse professer dumbledore
This is a very broad question, and not worded correctly. Severus Snape killed Albus Dumbledore in the end of the sixth book. Dumbledore had asked Snape to kill him, to save Draco Malfoy's soul because of the Unbreakable Vow that Narcissa Malfoy made Snape take in the beginning of the sixth book since Voldemort had ordered Draco to kill Dumbledore.
Because he couldn't get laid and needed to take out frustration on other men. It gave him sexual release.
Answer: By killing Dumbledore his soul would be ripped apart (like when Voldemort makes horcruxes). It is not the fact that Dumbledore would die, but the fact that Malfoy was about to commit a crime - namely murder - that endangered his soul.
Nobody.
Dumbledore wanted Snape to kill him because otherwise Draco Malfoy would have had to do it, or be killed. neither of which Dumbledore wanted. Because he is already slowly dieing from the Horcrux ring that he put on his finger (the reason he has a black arm) and because Voldemort ordered Drako to kill Dumbledore and Dumbledore doesn't want it on Drako's conscience. Also, Snape needed to kill Dumbledore to silence any speculation with the Death Eaters about who's side he is really on. ------------------------------------------------------------------------------------------------ Dumbledore wanted Snape to kill him so that Draco's soul wouldn't be damaged, ripped apart on his acount. When Snape asked "what about my soul?" Dumbledore replied: do you think it would affect you by helping an old man avod pain and humiliation." or something like that.
