So, Severus Snape actually loved Draco and truly favoured him! He wouldn’t have killed Dumbledore otherwise! He wouldn’t have taken an oath to protect him! I mean it is obvious why he protected Harry! He was Lilly’s only son and he could see her in Harry’s eyes! But why did he protect Draco so much? Why he cared about what’s best for him? Why did he favour him? It couldn’t only be to disguise himself as a secret Voldermort supporter! Severus actually loved Draco as much as he loved Harry but for different reasons! Severus had two sides! One being Draco and the other being Harry… His dark, cowardly side and brave, loving side! He kinda lingers between those two throughout his whole life until his love for Lilly made him strong enough to become the hero all Harry Potter’s fans know him to be! Severus Snape isn’t just an one dimensional book character! We can see pieces of his dark side through his relationship with Draco and I don’t think that we should forget or dismiss that since this is what made Snape such a fine example of a changed man who eventually gave his life to destroy the darkness that haunted him throughout his whole life! He did it for Dumbledore, Harry, Draco, Lilly and himself! He didn’t want to be the loser of the story anymore! He didn’t want Draco to be a loser! He didn’t want Lilly to have died in vain! He showed the way to Draco! Just like Lilly and Dumledore did to him!
