Elihu:
I think that Snape's and James's  mutual disliking was something 
which developed over time. <SNIP> If Snape had been sorted into 
Gryffindor, he probably would have made friends with the same kids 
as Lily, and his relationship with James would have probably ended 
up better.

tubazrcool:

I have to agree with Elihu. Snape did go into Slytherin, 
so naturally, he would have been around dark-minded people. 
Especially during those times, the people around whom one 
hung influenced them. I do believe had Severus been around 
the Gryffindors, esp. Lily, instead of the Slytherins, he 
would have been a different person. But, then the after 
effects of him being put into Gryffindor would have more 
than likely been detrimental to the series. Lily and James 
might not have married, Harry might not have been born, 
Voldemort would have taken over the ministry later on 
without fear of another "with the power to vanquish the 
Dark Lord" person coming along to destroy him, since Severus 
wouldn't have been eavesdropping at the inn during the time 
Trelawney was prophesying to Dumbledore. Many things wouldn't 
have happened and the series wouldn't have been the same. 
There had to have been a "Snape" in the series.
