I've only heard of such suicides from nearby congo's... but it was always explained away as the victim's fault...

Yet, the Bible’s words are not easily brushed aside: “God is not one to be mocked. [“There is no thumbing your nose at God.”—
Byington] For whatever a man is sowing, this he will also reap; because he who is sowing with a view to his flesh will reap corruption from his flesh.” (Galatians 6:7, 8) Lewd behavior often results in sickness, or even untimely death, from diseases such as syphilis, gonorrhea, and AIDS, to name the outstanding ones. Mental and emotional imbalance,
depression, and even
suicide are also at times the result of promiscuous life-styles. So while those sharing in immoral practices may laugh in scorn at those trying to keep themselves clean, the laughter stops as the mockers begin ‘reaping what they have sown.’—Compare Romans 1:24-27.
