This is my first post to the comm, so if I've grossly broken any rules, do say, and I'll fix them.
Snape's character has been hashed and rehashed since the end of DH, and his motivations and reasons for his actions have mostly come into question, especially regarding Lily and the Death Eaters. I confess, I haven't been able to go through all the numerous metas and opinions on this, so if I've repeated someone else's views, it was unintentional and I'm sorry for the repetition. I don't think I have, though, so we'll see. The theory I have is also not an interpretatin of canon, but rather, a motive we may be able to explore in fanon and in picking up where DH left off.
And it involves Severus' father.
At least, that's what I think. I hope it at least presents a different angle to look at things from. I hope it fleshes out his character more, because even after DH I didn't think he was rendered shallow at all (until I realized the interpretations I took for granted, were not what other people took for granted). Of course, this if more fanon-ish speculation than canon-analysis, but I have my thoughts on the pure canon aspect too. They're just for another post, some other day. :)
Cheers!
