How to evaluate Hu Hai, Qin Ershi?

Personally, I don't think Qin Ershi is very fatuous, but he was blinded by a traitor like Zhao Gao, but he was really wrong. If Fu Su becomes the emperor, I think the Qin Dynasty will also be devastated, because it is only a matter of time before the Qin Dynasty forcibly destroyed the six countries and the adherents of the six countries rebelled, but if Fu Su, he may solve this problem and pass it on to the Qin Dynasty.
