Both their sacred gears are different. Diethelm's Holy Resuscitation can ONLY heal people who is related to the Church. Asia's Twilight Healing can heal all races. So you're logic for hating Aisa and calling her a bitch makes no sense. What makes you think that anyway? What has she done to make you think that:

Saving someone who she thought was in need of help (who turned out to be a creep)?

Helping an injured child?

Doing something with Issei that Rias was going way before she even arrived.

Healing numerous people in battle to the point of near exhaustion.

Standing up to a freakin' Super Devil to protect her new family.

Michael himself didn't even what to excommunicate Asia, it was due to the imperfection within the System of God in Heaven due to his death that could have affected the belief that Angels needs to survive due to her sacred gear being capable of healing even Devils. (So, all in all, it is due to the people among the Church who overreacted at the first moment).
