Yes. Because even though everybody always makes Snape out to be this tragic hero (which I guess he is) just because he protected Harry when Lily died, they don't seem to realize that he is still an incredibly selfish character. He was perfectly happy to let people die. If Voldemort had chosen Neville, it would have been business as usual for Death Eater Snape, because he wasn't in love with Alice Longbottom. Snape didn't care about doing the "right thing." Ever.
