Swiftpaw wasn't fighting the dog pack. and it's a big stretch to say that Ravenpaw, Hawkfrost, Mousefur, Hollyleaf, and Tiny were killed b/c of Tigerstar.
This quiz is four years old, so I havent looked at it in a very long time. The actions of Tigerstar ultimately led to the demise of these characters as far as I can remember.
It says cats who died because of him, not who he killed, so they should be here. It's a stretch to say that Ravenpaw died because of him though, since he died a long time later with SkyClan.
