zgirnius:
I suggested in a post a month or so ago that this might be an 
indication that one or more of Snape's crimes might have been against 
someone who loved him. Voldemort has never committed any wrongs 
against anyone who loved him, because noone has. I would give a link, 
but the search function is not working properly.

There is also a somewhat less 'common-sense' idea, which would be 
that while Voldemort, as an intelligent individual, understands that 
his actions are illegal and considred wrong by others, lacks the 
capacity to understand this on an emotional level because he is a 
sociopath and has never experienced a meaningful connection to a 
fellow human being. Whereas Snape has, so he sould have knwon better 
than to join the DE's. etc.

--zgirnius, who would have sworn she has written the occasional post 
or two with the word "Snape" in the body.
