This kind of events actually fit in the SLO's central themes: survival, reality and ability. But, would the shinobi be killed and only one of them comes out?
Allied (or just friendly) villages generally used the chunin exams as a way to bring up new shinobi, show that they trusted each other enough to show off their jutsu, and (most importantly) show the nations they were fighting for that the money being spent to help with upkeep for the villages was well worth it.
I don't think "trust" was part of showing off the village strengths with the genin killing each other. Anyway it is true, the Forest of Death is [almost] the same shit as a "hunger game" although not all villages have the same chunin exams.
There should be 2 girls, and 2 boys from each village allowed to enter.
Allowed.... or forced? :O
