Can you please explain to me how that includes murdering abortion doctors?
You posted that contrary to being our brothers keeper we can only look after our own salvation. Scripture does not agree. Looking out for the good of your brothers and sisters, even those still in the womb, is your biblical duty as exemplified by the verses cited and literally hundreds more.
"Just as I also please all men in all things, not seeking my own profit but the profit of the many, so that they may be saved." Saving others must be the concern of every Christian.
Murder is prohibited by the word of God, killing is not.
