Im thinking Zack.
Before me there was hardship.( the war, and also the fire incident. Being in test tubes for 5 years)
After me there is only misery.(cloud losses his mind. things begin to downfall)
People exploit me, people are exploited by me.(errr)
Yet I myself do nothing actively.(you cannot controll him,and he is dead)
What am I?(what...er,human??)
i still say its Zack.
