Well, you show a text incorrect (don't exist) and out of the text. I will take your first quote for example:

In all Soferim 15, the work "killed" appear only one time and it's here

(Soferim 15:10)

the real text is: "R. Simeon b. Yoḥai taught: Kill the best of the heathens in time of war;"

Which very different from what you show...

Maybe you should verify next time
