Why doesn't Rosalia trust Abedo?

Abedo is from the outside, some of them are wizards from heaven, and there is an artificial weapon made by an alchemist in Kanlia, which is in danger of getting out of control. Rosalia can't see through him. In Rosalia's mind, protecting Mond's safety is the most important thing. So maybe a little wary, that's how I understand it. These two figures are both from Genshin Impact.
