World Peace?

[kurosh]

You can kill the person you care about the most and there will be world peace. Countless lives will be saved and many people will be much happier. However, you will not be directly affected in any way. No one you know, who would have died, will not die. The economy will not be better. You will never see these people who now have better lives. Basically, all you have is the thought that, around the world, there is no more war.

Do you murder the one you care about the most?
