وقتل النفس ظلماً
And killing a person unjustly.
Mentioning unlawful killing in the discussion does not license it. Human life remains strongly protected; one cannot treat killing an innocent person as an ordinary concession simply to preserve one's own life.
Coercion does not produce the same consequence for every forbidden act. A threat that affects speech or certain property-related acts must not be indiscriminately extended to an act that wrongfully takes another person's life.
