If an app can't be gracefully exited from using the Back button, it can be "force closed" from Settings/Applications. But if an app misbehaves like that a lot, it's probably a sign of something wrong that should be addressed (maybe by deleting the offending app or doing some troubleshooting).
Many people run task killers because they see a long list of "running apps" in Settings/Applications, and think that this is a drain on their system. As I've seen it explained, these apps are actually only cached in memory. Android doesn't need a large overhead of empty memory, and it likes to maximize memory usage by preloading apps (at minimal cost to resources) that it thinks you might want to open. Keeping them in memory once they are loaded does not require any CPU cycles. A task killer in automatic mode will interrupt this process, and Android will load more apps, which are then killed, and the process repeats over and over. This is actually a greater drain on system resources than leaving things alone.
PS. Here's a better explanation:
