Sometimes just one can mean more than 50 000.
What’s the point of this sacrifice if you haven’t even knew them?
What sort of sacrifice that? Of your own property? You could blew up a freighter filled with tritanium of the same cost for same effect. What do they mean for you anyway? Because I am pretty sure you couldn’t know whole 50 000 of people to treat them as persons. What kind of sacrifice can that be? Their sacrifice, maybe, but not yours. You can’t even remember all of their faces. Maybe just two, or free, am I right?
If you want to make a really meaningful sacrifice of the life… tell me, are you brave enough, are you devoted enough to sacrifice yourself instead of them? It is easy to take others life. But could you give your own life for what you believe in?
