BCSpace has a good point. The last book in the New Testament promises a future with far more Godly killing than what is reported to have happened in the Old Testament. Jesus may have taught human beings to be kind to each other, but the message that God is morally right in carrying out and commanding violence is entirely consistent throughout the Bible.
Incorrect. There is no godly "killing" in any manner that could be said to equate with what happens when one human being unlawfully kills another. True, the wicked are completely and utterly wiped off the face of the earth, but why is this cause for alarm (unless you are one of them)? There is then no more evil, no more immorality, no more crime, no more addiction, no more human misery caused by the evil human beings do to each other and/or foist indirectly on others through the poor or reckless use of their agency.
I'm not sure what is meant by the term "kill" in this context. The
bodies of the wicked will be annihilated, but their spirits will live on, eternally. God cannot "kill" anyone in any absolute sense.
An interesting exploration of this subject is found in the Bhagavad Gita, within the context of its just war theory.
