If the tournament payout is flat (like an entry) then fold. If the tournament is outside your
bankroll and cashing means making rent, then go ahead and fold.
Understand that against any Ax, you are about a 65% favorite. That does not mean you will win. That means you win two out of three. So is it worth having 80BB two times and being knocked out of the tournament once worth it? Most people would say yes.
Then there is the chance Villain has QJs or a smaller pair like QQ. Here you are an 80% favorite, again not a sure thing. You only double up four out of five times.
The Bubble is the time for big stacks to shove over every raise. Each time they get you to fold, they win blinds, antes, and your 3X raise. That's 5.5BB!
