I don’t think any individual is implicitly moral with regards to everything. I’m not suggesting everyone has the same hidden desires but I believe everyone has some instinctive behaviors and thoughts that they need to challenge rationally in some way or another. Philosophical frameworks for morality wouldn’t exist or be debated if it was unusual to need a rational framework for moral behavior.

Unless somehow every harm someone inflicted on another somehow affected themselves in the same way there’ll always be a selfish instinct that has to be overcome. If it was easy it wouldn’t be something to admire and respect as part of one’s character.
