yep! you're right again, sorry wrong choice of word. It is really an effect of seeing things negatively, making their-selves locked up in a dimension that is full of sadness, regretting what's done, thinking things that's hurtful until they bleed, world of hopelessness to be exact and because they're blinded by their own pain and experiences. That's when they won't have the will to live because what they're only seeing is the dark side of life.
