what did ya think about Sandman killing Uncle Ben?

I noticed a some people have problems with it cause they think its messing with Spidey's origin and that if Peter had stopped the other guy, Ben would've still been killed. Um........... yeah, if you really watch you'll see that Sandman paniced when he saw his partner and accidentally killled him! AND it helps make the movies another Spiderman universe. whatever thats my opinion. what do you think?
