> You are personally responsible and liable for anything that happens.
So? You are personally responsible and liable for a nearly everything you do in life. Typically, you'll only "go to jail" if you do something seriously wrong, and then the limited liability of a GmbH won't save you (whether you're an owner or an employee).
The limited liability of a GmbH refers mostly to financial liabilities in case of bankruptcy, not to, e.g., criminal negligence.
