If a person went a good way because you made more content to help tieflings (the bad hero does not get into the Underdark and goes to the Moonrise Towers in a different way) and did not make a normal motivated passage of the path of evil, many people did not even know that there was such an option, then does it make sense to publish stats 75% / 25%? It's a shame. If there was no charismatic Minthara, and people who were SPECIALLY looking for an opportunity to make friends with her no matter what, it would be 97/3% (3% just for lovers of chaotic evil)
Larian can easily reach 50-50 if they listen to their players who write feedback and hope to be heard. A lot of people who love to play evil complained that the game forces them to help tieflings
