It is a joke to say that monks can't kill people.

Innocent karma, harm to all beings, nature owes all lives, and the result of karma is inevitable. That is, what wise and blessed normal people should not do. If the environmental conditions are bad, the wicked are in power, and the lives of all beings are at stake, and someone can bravely kill thieves and save lives, it is naturally a good deed. Therefore, to kill or not to kill lies in understanding the cause and effect of good and evil, which is the difference between a wise man and a fool. If I could understand the Shurangama Sutra and Sanzang and understand the purpose of the teachings of the sages of Buddhism, I would not be confused by various phenomena.
