Why didn't Santi kill Luo Ji with Naoko?

Protons have the function of monitoring at first, but they have no ability to kill people. Just like a telescope, you can see it, but you can't influence it.

Later, after people created the body, they had the ability to kill, but at this time, the logical body was already tied to the gravitational wave launcher. As long as the logic dies, the three-body coordinates are immediately introduced.

Later, after Luo Ji handed over the sword-wielder to Cheng Xin, that is, when human beings immigrated to Australia, it didn't matter whether Luo Ji died or not.
