I've been seeing some people act as if Nika being a god of liberation and God of destruction as being two polarizing things, but honestly, I think it's one in the same, it's just that some peeps see destruction in this negative and malicious connotation, when it doesn't always have to be "evil".
As seen with Luffy, he liberates people and countries by destroying the oppressing force that rules over them, which gives the people the ability to actually choose their future for themselves. So basically, he liberates the oppressed by destroying the oppressors, a god of liberation through destruction.
Honestly, reminds me a lot of Mehrunes Dagon from the Elder Scrolls for all my Elder Scrolls fans out there, but of course sillier and wackier.
Of course, a lot of you probably already came to this conclusion, but I have seen some peeps in other sites that thought otherwise.
Now of course, there could be a fruit for both interpretations of Nika, Liberation and Destruction, but I think Nika's complete identity is a God of Liberation through Destruction.
