I think good can come out of a disaster like this, but not much. Even though a lot of people died, at least some people and small families survived the sinking of the Titanic. At least some people got the chance to go back to be with their families. Yeah, more people could've escaped, but at least people survived.
I do admit. The comany that built the ship were a little cocky. Since the company viewed the ship as "unsinkable", the company decided to keep a very small amout of life boats onboard. And when the Titanic actually sunk, only some passangers made it. But, some is better is none. It actually could've been worse. There could be a chance where no one could make it.
