In any church there are going to be 'bad' people who seem like they are trying to come across as perfect examples of the sect. Yeah, some are just hypocrites. And some may be troubled people pouring themselves into the religion to try and help themselves gain the strength to cope with and correct the rest of their lives. In my estimation, it is really up to God to decide who falls into which category. I won't let trying to judge their worth determine my own involvement in the religion, or let trying to figure out their personal struggles distract me from trying to fix my own shortcomings. The way I see it, there's no such thing as a perfect Catholic, Jew, Mormon, Pentecostal, Muslim, or anything else. And any time you start expecting anyone else to be more perfect, you probably need to pause and take stock of your own issues.
