If you believe that, then you're an extremely weak player. You don't care if they don't go broke or not, since they have already called preflop and given you plenty of equity. Also you make the horrible assumption that ALL you should be raising is A2, this simply isn't true. There is much a preflop raise does not tell your opponents, simply because Omaha is about 4 cards and not 2. If your game is so predictable that when you raise preflop everyone puts you on A2 and you do have A2, then I recommend you don't play Omaha/8
