[Dragon Ball] Why did Mr. Satan become such a big hero?

After defeating Cell he became a big hero and the whole planet admired him, thought of him as a super human being, and the savior of mankind. But assuming that everyone believed that Cell was a phony who did lights and tricks like Mr. Satan convinced them to believe then they shouldn't have really thought that he was a threat to the whole planet or think of Mr. Satan as that big of a hero for stopping someone who they thought was a normal dude with light shows and tricks.

Yeah they knew that Cell took out the whole royal army and killed thousands but irl you wont be considered the savior of mankind or become the richest man in the world for stopping a terrorist will you?

Beating up a terrorist who blew up countless military bases still is pretty heroic even if they staged it using bombs 

It's a bit like asking "Why are Mystery Incorporated famous for stopping crimes? It never turns out to be a real monster."
