What would you do?

1. I would kill the guy. He wants to die anyway, and I myself along with everyone else in the camp would probably prefer not to die.
2. One dying is better than the both of them. I would save one over killing both, but if the mother would become suicidal after the death of her child, kill the both of them.
3. No, he shouldnt leave his son. That's his child. He needs to stay with him & protect him. If the child will die anyway, then he should leave him. But, if he could live if under the protection of his father, then his father needs to stay with him.
