What per cent of people are playing honestly?

It seems to me that there is a large number of people using this site who use chess engines or unfairly use something that causes an unfair time lag. And I am tired of people trying to explain the time lag. I see games all the time where one player has 40 seconds left, the other player has 5 seconds left---they both seem to play immediately and in real time, yet time seems to add to the five second player and the 40 second player loses on time!!!!!!!!!!!!!!!!!  What kind of player actually feels good about cheating to win? How does that help an ego?
