Summer was one of that "silver eyed warrior" thing. Crow said that Raven has a very strange view of this world (and that she is dangerous). Maybe, just maybe ... Raven thinks that those "silver eyed warriors" destroy the balance in this world (because they are too strong) and therefore, she eliminates them, if they become to powerful.

This could also be the reason why Crow was always watching over Ruby - because he did not want Raven to harm her. It has been said that Ruby was taught to fight with her Scythe by Crow at Signal academy. Now that Ruby went to Beacon with Yang, she's under Ozpins' guidance. So Crow is not longer needet for her protection and can take Missions for Ozpin.

Now that Ozpin is gone (and Ruby showed a glimpse of her imense power!)- Crow needs to watch over her again (like in the scene after the credits).
