wormtail (spoiler)

hey guys i was just thinking that what if after all the humiliation wormtail may turn into a +ve chr.and join harry as a friend (i know that harry is never going to forgive him as he is responsible for his parents death,but what goes in supposing)maybe wormtail knows about voldy's horcruxes,i mean maybe he knows wht voldy's horcruxes are ,where they r and how to destroy them(i know i am expecting of too much but still it makes sense to me),as wormtail is good for nothing so wht's the point of voldy still keeping him maybe he knows something very important,its just my thinking ,so wht r ur views?
