Good suggestion @Rav. You could also work with the Demon Pendralion, @DarkestKnight did a QnA with him here:
You can work with who you want, although personally my suggestion is Archangel Tzadkiel, as I have experience with him. And no don’t worry they are not like that. When you’ve been around for a rather incomprehensible amount of time like them, understand humans well, and can see into someone’s deepest desires and understand then better than they can most of the time, then you don’t have a personality that stems from weakness and a lack of understanding like that. Some people evoke them and interpret them like that because it’s mostly their mind that does the talking. As the channel of communication changes, the spirits they know also change over time.
My thread here is a bit related to that:
Or, they expect angels to be like that so either their mind makes them to be interpreted like that or they summon a weird egregore of the spirit they want. So don’t worry, the true nature of the Angels aren’t so inexperienced and not quite so normal human-like. I also personally do believe it is their duty to help those who call them (Note, I am talking about Judeo-Angels here). Demons as well as @Darkestknight has also said.
