First off, it’s Lily* Not Lilly.

Secondly, because someone has a bad childhood, it’s okay to because a Death Eater? No. I can sympathize with him, however under NO circumstance is what Snape became okay. It’s not okay for anyone, for ANY reason, to become a death eater. Lily was his friend, and he knew very well that when he started hanging out with those people, that his relationship with he was going to change. Whether he realized he was wrong and tried to make up for it, it still doesn’t make up for the fact that he caused Lily and James’ death.

Severus should have been a real man from the start and dealt with his problems with a bottle of whiskey. His actions were forgivable, had he stopped hanging out with Mulciber and stopped with the dark magic, but he didn’t. That was the only way Lily would have forgiven him, but he couldn’t even do that. 

Had he changed, and became a better person their 7th year, like James did, maybe Lily would have chosen Severus. By the time Severus changed, Lily was dead. No ones fault but his own.

Don’t hate on James cause you know I’m right.

…So, if I hadn’t returned James’ love and he went off to become a death eater, it would have been justifiable had he taken care of my child? I think not. Had Severus not gotten into the Dark Arts, started hanging around Mulicber and Avery, and call me a mudblood, maybe things would have ended up differently for him. But, he chose his ways, and I chose mine. Sure, he made up for it later in his life, protecting Harry, however it was too late. I was dead, and things like that can’t be undone.

Uhhh, and Snape did? He was a fucking death eater. He took part in the plan to eliminate muggles and muggleborns. Which makes him a hypocrite and just as much a bully (or more so) than James. James may have been a bully, but he wasn’t a sadist. 

Put that in your pipe and smoke it!
