You know, it really all depends on their mission. Anything that's a deterrent to their mission is grounds for abhorrence.

Like anyone who stops Suriel from achieving her goals, who tempts her to hurt rather than heal. Who hurt the people she heals, would likely be the ones to gain her ire. But, essentially, it's mostly just demons and even some angels adopt a 'don't really care for them' policy, as long as they don't mess with them.

Daniel's one of the most poor excuses of a demon, though. His envy extends mostly to himself and his overprotectiveness, wanting to keep those close to him safe really no matter the cost. He survives through residual temptation from strangers 'cause everyone's envious of something - he goes for the natural cut rather than trying to siphon the energy for himself.

Michael's also a poor example of an angel and kind of hates everything about himself, so... he can't really hate anyone else when all of his hate is directed on himself.

But, yeah, I think it's more to do with their mission and their personal convictions than their ties to Judeo-Christian canon. I think angels tasked with purging are more likely to hate Others that aren't angels a lot more than just your run of the mill angel who's a guardian or heals people.
