About Nazis:
I don’t get how it’s morally okay to give money to rescue a Jew to an organization that is using that money to kill more Jews.
I see how it could be a loophole halachically, since one is knowingly rescuing one life, and indirectly maybe killing more lives. Yet it is not a direct transaction.
However then there is the whole impact of feeding into and reinforcing their patterns of behavior of hostage taking to fuel their terror.
Then again… if I had a way to rescue a loved one, then I think that I would do whatever it takes. That’s not a situation where I can sit on my high horse here criticizing. For sure I would be in survival mode, and unfortunately my brain would likely be highjacked by the conditions, deprivation, and such that anything would be possible to rescue someone I knew, or even didn’t know but was right there.
