That’s provably not universally true, although I have no idea about the exact demographics.

Best I’ve ever seen was some online discussions about motives, but I never compiled any statistics out of random anecdotes (that must be biased and probably not representative).

If they weren't motivated by a toxic sense of self regard and a desire to humiliate others they wouldn't cheat. This is axiomatic.

That's a gross exaggeration. Some people just want to play the game, but lack motor skills commensurate with their other abilities.

Are players who take advantage of developer-supplied aim assist and other assistive technologies "motivated by a toxic sense of self regard and a desire to humiliate others"?

Are people who play the game as the developers intended using the tools the developer supplied cheaters? Wow, deep philosophical questions there.

Gonna have to ponder if people who aren't cheating are cheaters.
