unfortunately there is no real punishment for killing someone indirectly like that. i will tell you about my grandpa. he was a farmer and making horseshoes in what was germany at that time (prussia, today polish). he had 6 kids with his wife which was normal at that time. they took him in to the SS forcefully because he had the genetics and they were lacking in numbers. the SS members got a blood group tattoo. he fought in the eastern front which pretty much was living hell if not worse. they were literally eating corpses of their frozen comrades because there was no food. he got deported into one of the worst soviet gulags because they could identify him as being part of the SS because of his tattoo. he only survived because he developed a strong will to survive because he wanted to see his wife and kids again and tried anything to survive. he could speak russian and managed to make friends with a higher up russian guy there and crafted figurines for that guys kids (made of wood and colored with his blood and chlorophyll from random plants). in return he got slightly better treatment and more food. this is the only reason he survived, he watched other inmates die by the hundreds. he got released way after the war was officially over, in 1952 or so. he got back somehow but they lost everything. their farm was part of the soviet union now and they never received any compensation for that loss. he built up the family again but it seems like the whole family life wasnt that great after all and his wife was not treating him well ( he was gone for a long time. i kinda think that she assumed he would never return and had other guys ). the sole reason for his strong will to survive was to come back and lead that fantasy happy family life and it just shattered right there. his will to live was gone and he hanged himself.
