"The primary role of the relatively untrained pilot was to aim the aircraft at its target bomber and fire its armament of rockets. The pilot and the fuselage containing the rocket engine would then land using separate parachutes, while the nose section was disposable."
Eventually, these tactics are not that crazy. In war, lives and machines are expended to reach a goal. If some tactics seem crazy, then only because that fundamental fact is harder to ignore.
I think it is important to add, that, in contrast to japanese tactics, the german pilots were not necessarily expected to die. It was "just" extremely risky and a bunch of them did actually survive.
The pilots were expected to parachute out either just before or after they had collided with their target.
The fighter pilots ramming bombers were expected to bail out. There were survivors.
The pilots of the Leonidas squadron were expected to "self-sacrifice" in their attacks on bridges. They faced rather less social pressure than Japanese pilots, though.
