Kazuya you actually have a reason to kill Jin cause Jin has your other half devil and in Tekken 4 kazuya ending it showed that you wanted to take your other half from Jin but miserably failed and got your ass kicked
Actually. Not anymore. He's already unleashed his true devil powers to its fullest so in actuality, he doesn't even need his power no more especially since Heihachi is no more. Long story short, he considers Jin's devil gene obsolete now that he has unlocked the power of the devil gene to the fullest. If anything, he wants to reconcile with Jin now that he's fulfilled his goal of revenge.
You know when you ask me it makes a lot of sense kazuya would be relieved his mother and his father started the whole thing second his mother tried killing him she made kazuya have the devil jin in the first place so her dying would totally be a relief tp kazuya
