Gravis watched as the discussions broke down and force was used. Would he get involved?
No.
Why should he get involved? Just because Joyce was a woman? Cultivation didn't take gender into account. The cultivation world was different than the mortal world. In the mortal world, one person couldn't have enough power to overthrow whole nations, Clans, or family heads. People needed help from other people in the mortal world since one person just couldn't reach overwhelming power. For mortals, the cooperation between humans was necessary.
Yet, in the cultivation world, this belief would break down. When there were no rules to stop someone from committing all sorts of things that mortals would consider "atrocious crimes", the strength of a single individual became more important than the strength of a group.
