You can have programs crash in any language. However, it is the question, how well a program can recover from an error. Having a concept of error handlers in the language, which can catch conditions occuring inside the code they are calling, leads to more robust programmers. Think of it as airbags and seat belts. Drivers, who don't make a mistake, wouldn't need them, but in reality shit happens, and they give us more survival chances.
