How funny

Olivia just wondered how many screws loosened the grandpa's head to actually lead his entire family into ruin.

According to what Olivia discovered, even if the man's children decided not to work for the rest of their lives, the wealth that man had could sustain them, yet he was obsessed with making his kin struggle to the point of losing their mind.

Caroline had confessed that suicide could be the cause of death, because the day William had first told her about his life was the day she caught him trying to jump off the roof of their school building. 

The boy had been trying to escape his life and although he found happiness in the woman he loves and his child, he was left with choices. 

Either to keep his wife and children in his world and let his child end up like him, or he let them go.

He had let them go, but couldn't deal with life without them, hence killing himself.
