Individual jews can be redeemed spiritually by *wanting* to not be lying thieving parasites, and this will be very helpful for them ... in the next life. Barring a *major* miracle, such repentance won't fix their genetics, so these jews and their descendants will still be a threat here and now. Fully embracing the technological implications of Darwinism *would* eventually fix their genetics, but as you said they are afraid that a proper understanding of Darwinism would help the goyim SEE. The cause of their destruction will be their rejection of the only tools that could save them.
