For example, I don't think it's in my interest to defend or die for the German state. However, I would use violence to protect my life if someone tried to kill me or threatened my life directly. The German state would interpret this as a political objection rather than a conscientious one, since I am willing to use violence in principle. If I could convince them that I would let someone kill me without defending myself because I categorically reject violence for any reason, they might consider that a conscientious objection.

Yes, as I said, after the Cold War, Germany no longer wanted to maintain such a large army, so they started accepting any reasonably well-written argument. But in any war, you can see that nation states will start struggling to recruit new soldiers as it becomes obvious to the population that it's a rather pointless endeavour to die for their state. So, they start forcing people. We've seen that in Russia, Ukraine, Israel, USA, etc.
