So, you like a pure and noble character whose dogma is to enjoy little things in life, avoiding temptations like money, women, power and if needed, to protect the lifestyle that faith gave him. Yet you encourage him being unfaithful by having affairs with kitana (even if the "plot" in previous titles was stating that all is good).
Shaolin monks in MK are not the same as in real life, otherwise Great Kung Lao wouldn't have descendants and Liu Kang, Kung Lao and Kung Jin would've been bald. So it seems that in MK a Shaolin monk can love a woman and love is not an evil emotion. Love actually inspired lots of heroes to become heroes they are known as (Superman and Lois Lane, Spider-Man and Mary Jane, The Hulk and Betty, etc.). Liu Kang just happens to be in that category of heroes with love interests that serves as one of the main sources for his inspiration to do what he does the best - good. Maybe growing hair and having a healthy romantic relationship is just a benefit of The White Lotus Society, who knows.
I don't get it, do you really support a sense of duty or any "hero" they feed you?
I like heroes that remain goody two shoes boy-scouts no matter how much a hard time they might go through in the story. It is their ultimate believe in good and doing the right thing is what the most important. Original timeline Liu Kang was doing just that. Canonically he didn't even killed a single person throughout the 7 main games of original timeline and gave formerly evil characters a second chance (like Ermac) and helped others to redeeme themselves who made mistakes in the past (like Shujinko). He believed in second chances, which also an important heroic quality.
I have one more, hope it's not much to ask. There are literally thousands of game titles since 1990. Out of all these, MK was the first and most iconic title that had violence as its theme. Other fighting games weren't like this. SF had nationalities, VF and Tekken had martial arts as their theme. But, MK was like the "horror genre" for fighting. Endings that favor bad guys, plot full of treachery and backstabbing. MKDA's intro and MK9's trailer literally had protagonists killed (WHICH IS FUCKING AWESOME because almost no developer goes that far).
Liu Kang was the sun of Mortal Kombat universe, a goody two shoes hero who standed out in this gruesome saga as the last hope. This is actually exactly what made him so great in the original timeline, it is because a character like him existed in a dark universe like that, because reamining good with all the shit going around you is what really takes most of character's strength, courage and virtue and shows his true potential and power of his soul.
So, why don't you play captain america in marvel and superman in IGAU instead of rooting for a nice guy in the bloodiest game ever?
I play all of these games, but also want my favorite hero in Mortal Kombat to be back once again, because it is my favorite franchise of all time that once had a goody two shoes Shaolin super hero firebender.
I probably should also remind about that Liu Kang's fatality in MK1 doesn't even kills his opponent, but knocks out. He remained this fatality in MK2, but as further this series got, the more MK developers stopped caring about including characters personalities into finishers, only their unique abilities. But as I said, canonically Liu Kang didn't killed anyone in original timeline.
