This is not the only remaining option. You just want to kill more and more. Poor lambs.
If you start the game, you will have a carload of canned food, and you will have enough of them until the first harvest.
But you just want to sit and shred poor baby lambs who have not even had time to really grow up, because you are too lazy to raise your ass and do farming, fishing, traps, go to the city for provisions and, in the end, picking berries.
Yes, I am for morality, ethics and red lines. If they are not adhered to, the game will die or turn into shit. Everything has a limit. If you don't like it - develop your own mod and kill as much as you like. But I am against it. It's my position.
