More crap I keep coming with. These are things I wrote in a Youtube comment section btw, I just expanded on it a bit more to post here. I recommend checking out Cynical Warlock, he's got some great videos on Mortal Kombat.
I wish we were given a story mode that not only reintroduces Shujinko, but also the kahoots he got himself involved with outside Onaga. Like lying to Hotaru about King Zeffeero, and spreading chaos in Seido for Havik in exchange for coins (it’s a tiny side quest in konquest mode where the player bumps into Havik in seido). Have Shujinko be a righteous man who has no clue he might be insane, if you count randomly punching civilians and thievery to be a part of the story arc. He’s an agent of chaos that is unaware of his chaotic side, and Seidans can smell it on him, so a lot of them stay clear of him. It could explain why he turned on Liu Kang and the others in Kung Lao’s ending. There’s a quiet evil lingering, but it doesn’t want to take things over, it just desires to cause trouble.
I hope Shujinko plays a part in the Titan Havik story, because in my opinion it'll just feel wrong if he's not there since he's the reason we know of Choasrealm, same with Hotaru. There needs to be Hotaru, he's the order to Havik's chaos, and Shujinko is the child caught between those divorced parents.
I'd like to believe that Shujinko is also a mirror to Shang Tsung in a way. He (unknowingly) does bad things in the name of good, but Shang Tsung is (cartoonishly) open about his wickedness. Both of them have the ability to copy others, and were promised some form of grandeur, only to be double crossed by the very entity that brought them up. It seems with the mk1 timeline that their stories were swapped. In the old timeline Shang Tsung was a champion for Earthrealm who decided to switch to the dark side and learn soul magic, only to betray both his masters once the opportunity came. In mk1 timeline Shujinko supposedly comes from nothing, and once he becomes powerful he has to be subdued with his memories and powers taken away. He even has the same hairstyle as Shang Tsung, they must be mirrors of some kind.
I also headcanon that Mokap is descended from Chaosrealm. He's some random motion capture guy, but seems okay with the bloodshed that's going on. In Deception's Konquest mode you'll catch him strutting around with a big smile on his face. If you punch him he won't do anything about it, he gets back up and starts strutting again like nothing happened.
