If they can deport criminals to war zones or places where said criminals may face execution or torture, they can do that with you too

But Afghanistan isn’t a war zone anymore and there’s no evidence that these individuals are going to be tortured. If there was credible evidence that this deportations would lead to state sanctioned torture, then you would be right, and these deportations should be halted. However, Germany has made similar deportations in the previous years and there hasn’t been any reported incidents of torture of any of the deportees.
