How many People has Spiderman Killed?

Hey guys, i'm doing an article and I'm trying to figure out how many people has Spiderman actually killed.

I found this article (http://ift.tt/1PERDCS), but apart from a few obvious ones, is it accurate? I'm thinking he's killed 7?(whether they came back or not doesn't matter) Moondark, Drom, Charlemagne, Whisper-3, Shade, Digger and Morlun
