I'm for folding. We don't know anything about the tendencies of the other players, but we do know you have 2 opponents who can hurt you (P-1 and the BB). If both come in, best case is where both have smaller pairs. Even though you are 4-1 against each individually, you're only about 2-1 against both, because you now have to dodge 4 cards 5 times if you don't improve. Worst case, one has a smaller pair and the other has AK or AQ and you have to dodge 8 cards. If my math is right, that makes JJ less than even money. Even a 1 in 3 chance that you will end up with too few chips to fight on is too risky for my taste. And of course if P-1 has one of the "big three," you're a big dog already.
