It's great for levelling the playing field of finance. In traditional finance only the most capitalised players are able to do small arbitrage opportunities, and many firms make billions of dollars this way. In DeFi anyone can take advantage of them using flash loans.

Ok... how do you repay flash loans when things go bad?

Please, do elaborate.

Flash loans only happen if they're paid back. Pretty cool tech actually as someone pretty skeptical of blockchains

Flash loans are repaid instantly in the same block. If it doesn't repay itself the transaction isn't valid.
