Well, there is Armageddon, which looks pretty painful and terrifying in illustrations. But if you die before it comes, you get around that.
I was thinking about that, but I don't know of any promise that JW's will not suffer during the big A (correct me if I'm wrong). There is only the promise that they will survive it. Then they build the paradise in which there will be no suffering. Wow. It could almost be interpreted in a more general secular way - one group has "the truth," i.e. knows how things are supposed to be, there is a big war that wipes out everyone except those in the special group, the special group survives and builds a paradise. Just a tangent there.
2) You risk your family if they decide to kick you out because they decide you aren't good enough including the items listed in #1 above.
I think this (also applied to friends) is one of the more meaningful threats the JW's present. I could see how people who don't care about ceasing to exist or riding lions, etc. would still participate in this group just to be able to interact with their friends who would otherwise cut them off for the most part. Quite a threat indeed.
