Why the people run from home and become saint,sadhu, baba,what they want to fulfil and how they affect society?

It depends on whether or not you're already a JW. If you're not yet a JW, the JWs would tell you go ahead and question by doing research on JWs in JW publications and at their official website. (You're sure to find unbiased information about them from those sources, right? LOL.) But just don't pay attention to apostates' "lies" and opposing family members and everyone who criticizes Witnesses because they are all a part of Satan's world. If you are already a JW, then you're supposed to accept without question, everything the JW organization teaches. You must trust the faithful and discreet slave because Jehovah and Jesus trust them. And you know Jehovah and Jesus trust them because the faithful and discreet slave have told you so and what they say is trustworthy because Jehovah and Jesus them. Or do you want to be labelled as prideful, spiritually weak, independent thinking, or . . . apostate!? Do you want all your JW family to not speak to you ever again?
