Its an extreme version of correcting the loci of control from external to internal.

Most people love to live in the external loci side, because they can blame things on external forces and then not have to accept any responsibility to improve or change based on the outcome. Its a self defeating cycle because it never moves you forward.

Internal forces you to blame yourself, and introspect on what actions you took and the consequences of them. Often times in ways you'd not grasp on surface level thinking. Even when its completely wrong and you straight up had zero control over the outcome, you are still working on yourself regardless.

Its basic psychology, being applied by Assholes who think they are rediscovering the wheel, but its not wrong. And in this case, its almost certainly more helpful. It has nothing to do with the women, because they are prizes to be consumed.

Because if a hoe cheats on you and you just move on because that's what sluts do (it is, no lie there), what did you actually gain? If you put some blame on yourself, now you've got motivation to do a few more reps, to speak a little better, etc. Even if you are in reality, blameless.
