Prof.Snape was the most valuable asset that Harry had against Voldemort. Wouldn't you say?

Prof. Snape was not only the greatest asset but the final nail of insult to Voldemort. Taunting him with the fact that Severus hadn't been there all this time out of loyalty to him or even fear but revenge. As a teacher he was at the top. He maintained his focus and despite personal anger and hatred towards James he forever kept Harry's best interest in mind for his final show down. As in the pic I post with this answer you notice Severus stands between Harry and Voldemort were he always stood.

Of course he was! Though he hated James, Lily was his only love and he had to protect her son. That became the aim/meaning of his life. So he was always protecting Harry against the Deatheaters and Voldemort. I think that he would rather prefer to die than to admit Harry's death!

And so he did, lily!!! dont you rememder??? Snape gets killed at the end on hands of Voldemort... that socked!!!! But im glad Harry recognizes Snape's effort at the end... I think Snape is the most wonderful character in the Harry Potter sequel!!!!

Yeah but that *idiot of harry didn't thought soo even if he didn't knew and that snape was mean and bad with him Severus Snape was the most valuable thing Harry had against Voldemort
