Some of u guy just too narrow minded...hinata turn evil would be a twist to the entire show...it would just show that not only the uchiha are capable of strong emotion...an it would even be better if her turning evil would give rise to a new ocular jutsu...come on ppl think outside the box...or shut up
Honestly, that doesn't make any sense.
The Byakugan is all based around Taoism.
The Gentle Fist style is based around the Bagua Zhang style of Taoist-influenced martial arts:

The Chakra Network and a portion of the Hyuga fighting style are based around T'ai chi ch'uan:

We haven't seen much of the Gentle Step - but it would make sense, given that when Hinata used it - it was a rapid forward motion that seemed to set up similar to a spear thrust (also the animal theming).
Part of the key concept of Taoism is harmony and unity with nature.
It can easily be argued that the strong selfish emotions associated with evil actions would be an inhibiting factor to a Hyuga's access of higher tiers of performance.
