Why BvS is the sequel of man of steel instead of mos2 ?

9 months after BVS Introduced me to DC world, I still believe “man of steel” and “bvs” which directed by Zack Snyder, are both Masterpiece.

But I constantly saw some news or articles like this:

In their option，after MOS just”Skip” MOS2  to introduce Batman to DCEU is so”RUSH”. And almost same peolple Claimed everything they had ”issue” with gonna make DCEU doomed.

These articles really bothering me.

I never thought BVS was a rush project, But haters just keep saying that,  In fact, those are nothing more than self-centered accusations with no basis on facts.

I fought a war against haters in Chinese social networks for almost same length as I became DC fan.Second hands rumor Affected DCEU’s box office and Damaged zack’s reputation in China.I was outraged. And when I got mad about the fandom stuff, only thing can calm me down are these two movies. I could re-watch them countless times .To my surprise, last night’s re-watch was very productive.（mmm…very Alfred ）

When the fight night scene appears, I found there is a probably Parallels in the film.which matches up another scene in Man of Steel perfectly.

Then something just came up to me Suddenly. I just Solved a puzzle I don’t even know was there.

We all remembered this scene from MOS，before Clark escape the ship

Jor-EL said :  You can save all of them.

In fact ,for me ……….I always think this line kind weird and too ego for a Jesus character like Superman.

Because in MOS He didn’t suffer that much, Especially physically. Then after I rotated the screen-cap of BVS Fight Night scene. The Parallel across two movies shows up.

I finally knew Jor-El never finished that sentence He said in MOS. And This line should be like ：

You can save them all. but, You have to give yourself ( your life）first.

Then Superman started he suffer from BVS’s world, Distrust by people he is helping ,witnesses to make false accusations against him（Matthew 26:63）,summoned to hearing ( Matthew 26:65-68; Mark 14:63-65), but he keeps silent,（Luke 23:4）Until He confronts Gotham Bat for his mother’s life. Then physical suffer started with the fight, He had been beaten ( Matthew 26:65-68; Mark 14:63-65) Tied with ropes (Luke 23:2). “He saved others, but he could not save himself ! ”(Matthew 27:41-44.) He almost killed by the Bat. Drown in water. In the End, He was killed by Doomsday’s sting, Nailed through his chest .（Matthew 27:41-44.）At his funeral, people Careful and thoughtful placing of His body in its resting place inside the tomb.(John 19:42)

Finally ,Parables from his Kryptonian parents become to real.

He’ll be an outcast.     He’ll be a God to them.   They’ll kill him.

He completed his journey as almost like Jesus himself.  Given his life to saved us all.

So, you tell me guys. Could we still see superman’s journey in these two movies Separately?

Did these two movies have one same story-line for him?

About an alien among us, who went through most severe trials，Sacrificed himself, to saved and inspired us. The man we knew gonna come back for his next journey in justice league,The man gonna come back for us. The man we call Superman.

Whether It was planned like this at the beginning  of  DCEU’s production. or Clever adjustment later. As the question in my title,

why BvS is the sequel of man of steel instead of mos2 ?

I am satisfied with my answer here.
