It's pretty obvious from its continued and unwavering support for a nation led by Fascists who openly describe as "human animals" the neigbouring people from a different etnicity which they have oppressed for over half a century and are now outright massacring, commiting all manner of war crimes in doing so, that the "never again" that the German elites claimed to have learned is not at all the Humanist "nothing like this should ever be allowed to happen again to any people because of their etnicity" (which would see Germany react towards Israel as they did towards Russia when it invaded Ukraine) but rather the very specific and Racist "We should not have done that to Jews".

I too used to believe as you do, but what we are seeing right now in their actions, especially the massive contrast in their reaction to the victimizing of the Ukranians by Russia and the already much larger victimizing of Palestinians by Israel, is that whatever the German leadership has "learned" was not the Humanitarian Principle but something else altogether and the most obvious explanation for their very overt support of the Genociders in this specific situation is that it depends on the etnicity of the victims and the perpetrators whether such a massacre is acceptable or not in the eyes of said German leadership, which is pure, unadulterated, racism.

At this point Germany is activelly siding with Fascists doing the same style of action as the Nazis (though not yet the scope, but the continuing blocade of Food, Water & Energy to Gaza might very well lead to that). That is not the actions of a land whose leadership has genuinelly learned the lesson that massacring people because of their etnicity is Evil.

When it really mattered Germany showed that not only it's doesn't at all care for the plight of the victims but even activelly supports the genociders if the etnicity of the victims is not a favored one whilst that of the genociders is. One can then only conclude that all that "charity" was not done for humanist reasons (no humanist would support Israel after all they've done in the last month) and must have been the other reason for overtly doing "charity" - the cold and calculated managing of the image one projects.
