Suppose that two individuals who are in desperate need of some life essential resource, such as food, both happen to spot (at relatively the same time where it is unclear who saw it first) enough food (that we will assume is abandoned property) to ensure that exactly one of them will live. We will assume that both individuals accurately perceive this situation as, with high probability, the only opportunity for them to eat before their demise. Understandly, they will struggle for the sustenance. We will assume that the struggle ends with one individual fatally injuring the other.
What should be the legal repercussions in this situation?
How is the individual who slayed the other morally accountable?
Needless to say, the act of killing under these circumstances should be much less severe as opposed to killing for food when there are many other viable avenues to obtain it. Nevertheless, I am still unsure about the details of the argument to resolve this situation.
