Death takes part.
The wounder of life. Will they see what life is like once something goes wrong or are they to blind to see the bad? the love? or the good? Maybe they focus on one thing.
People learn to work together and focus on one thing at a time to try to fix these things that has happen to occur at this time period of there life.
If they do not figure it out then all life will be gone but though's who made it happen.
