This is an interesting question.. Hmmmm.. Would depend on the REASON for self termination. ‘Severe chronic pain’ I think Jesus would understand.. During the Civil War a soldier returned home only to find his entire family slaughtered. Would Jesus understand him committing suicide? I believe so.. Now, killing yourself because you lost a large sum bet, not so much. THAT would be greed and selfishness that led you astray.
Sounds relative...
