In Judaism there is also a sin after which one cannot repent and therefore, cannot receive forgiveness, if I remember correctly -- suicide. Though my memory is cloudy,
If you come across a ' suicide' verse or passage I hope you will post it.
Do you think Adam committed suicide ( self murder ) ?______
After all, Adam knew full well in advance that eating the forbidden fruit would result in his death.
Eve was deceived, but Adam was Not deceived.
Being created with perfectly sound hearts, mind and bodies they could only sin on purpose.
Adam deliberately, on purpose, willfully broke God's Law which carried with it the death penalty.
However, after eating, Adam did Not take away his own life by putting himself to death as a person would do so today.
Adam, like Satan, showed no remorse nor repentance and was Not forgiven for his intentional sin.- Genesis 3:19
In Christian Scripture the unforgivable sin is Not suicide, but sinning against God's holy spirit - Matthew 12:32; Hebrews 6:4-6
Mental illness inflicts many people, so Not being in a right state of mind so to speak, then how could suicide then or now be considered as unforgivable ?
