And heck, it works.
You play Russian Roulette. You win (meaning, you didn't die). You conclude that you're good at Russian Roulette and decide to play again. And again. And again. I suspect you know how this story is going to end.
Could it be so simple
No, it isn't that simple.
or am I going to mess up other stuff up?
Yes. You're playing Russian Roulette with your application. Eventually, your application will crash in a way that is almost impossible to debug.
