I don't think he necessarily likes Guybrush, he just needs a human being to help him out. Of course, he'd never admit that, so he covers up his shame with a lot of evil rhetoric. As for Guybrush, I think he does indeed find Murray amusing, like Monkey Mania says. In short, I'm not sure if they could really be considered friends, but they sure make an interesting duo.
Yeah, I suppose that makes sense. I've always thought that Guybrush likes Murray a lot more than Murray likes Guybrush.
