A bit of a guild predicament

Ever since I came back from a long break a few weeks ago, I've been in this guild and make a few friends in it. I've slowly come to realize, though, that 75% of the people in it hack. I don't want to be guild-less or abandon some of the people I enjoy talking to, but I'm really uncomfortable being around so many hackers. Should I quit? If I quit, are there any friendly guilds in the chaos alliance world (what do you even call it now?) that would be willing to recruit me? thanks
