I don't think you become the best or second best player through a mindset that includes "I'll cheat if that's what it takes to reach the top".
It is possible that some people can reach quite a high level but top out in their natural abilities well below the absolute top of the game and be incentivized to cheat to break through their personal, natural ceiling.
Even worse than "some people are cheating to make it to the elite level" would be "everyone at the elite level is cheating, you can't compete without cheating".
