colebiancardi:

and I am not sure that is what Dumbledore was saying either...DD
stated that Snape had remorse and regretted that the Potter's were
targeted, but I do not think that was the defining reason why Snape
turned on LV and decided to come to DD in the long run.  I think it
was something else, something that we will hopefully find out in DH.
