If you think only bad will happen, then of course you can't make good happen. Because you give up and stop trying.
If I did that, if Watanuki or Allen did that, Persona would be dead by now. King was killing her in the Arena. And what happened? Everyone placed a bet maybe we could do something. They distracted King, they started a riot, and it's because they believed we saved Persona.
It's because people just believed that, for once, no matter how horrible their lives were, that something good could happen that A LOT of people found real happiness. Found a way to keep going and get happiness for themselves and others.
