Kindred feels She's an Undead Abomination, regardless on how Senna came to live once again.
A quote : You can live countless lives and feel like an eternity, but only DEATH IS PERMANENT which means, she wasn't really that DEAD.
And Kindred will make sure Senna will find her peace either way.
Off Topic now: In Supernatural when Dean first met Death and IT said:
I am Death, my job is to rip anyone who's up for my realm, regardless of how they spent their lives (Good, Bad, Worse ETC) I am as Old as the Universe and God, when God's time will come an End, i will RIP HIM TOO!
