You are asking a impossible question because she has been far removed from this happening since she was the first person to be killed by Rias there was no forgiveness for what she did, and she personally caused Issei a great deal of pain and misery.

The action of Raynare killing Issei messed up the relationships of Issei towards all the girls it stunted his growth as a character for a while it took  a great effort in all the girls to confront this fear that Issei had this is what pissed me in the Anime by classifying this problem as a magical curse by Loki.
