Preflop: You have to maximize your chances to knock out the short stack. Calling is fine.

Post flop: You have to assume you cannot win this pot.
If you have some piece of the flop, then calling is fine because if your piece (Say third pair) is beaten by the big stack, then hopefully he'll knock you both out at once and you'll claim second place.
I don't think that the total miss here warrants wasting the chips, you just have to assume you're not being pushed out.

What would you do if the big stack raised you preflop?
