There's probably more to it than that, I'd think comradary, and shock value plays a big part in being a member. Plus, many do the whole orgy thing, which might lend a little inticement to the younger folk. They hate Christians, yet pretty much rely on them in a way. (from what I understand, lol!) They have their rituals, and masses, but it all comes down to freedom. Why anyone would feel the need to join a satanist church is beyond me, but many do and I suppose it's because they somehow gain some satisfaction from it.
