Sure! It depends largely on the specific program they're using, so let's suppose it's a program for decentralized gambling. Users would place bets on a certain outcome, and the program automatically pays out winnings based on the result.

In this scenario, Alice or Bob might be tempted to cheat by manipulating the odds in their favor. They'd be unable to do so, however, since the logic gates are permanently embedded in Bitcoin's blockchain, and can be publicly verified there at any time. The program could also be set so that any attempt to cheat would result in a loss of funds for the cheater.

BitVM's structure, with its transparent logic gates and on-chain challenge mechanism, is designed to deter such dishonest behavior, and ensure a level playing field for all participants.
