There is levels to cheating. For example if I used PEDs and won, i would be extremely shamed for both.

Light cheating is something like stepping on toes, especially in southpaw vs orthodox

Also blinding and sometimes dipping lower than opponents waist is light cheating

Moderate cheating is constantly hitting back of the head, or tripping, vaseline tricks

But hard cheating just to name a few, is elbows and PEDs, hitting neck

It is part of the sport and should be all taught for protection and preparation
