People in general certainly get wracked over this issue. Most religions and reincarnation-based belief systems seem to import serious punishment for suicide. This ranges from eternal damnation to being "forced" to relive the life or the circumstances of the life aborted. One writer (can't remember who) even said that we come back and must suffer the suicide of a loved one - which would require another suicide, presumably launching yet another cycle of karmic punishment!!

It seems that a large segment of humans are determined to have punishment for what clearly is one of the most profound personal choices a human can make. Even people who claim to believe in free will mostly assume there is no freedom to suicide. But certain types of suicides are widely accepted as a form of valiant self-sacrifice, like the soldier who throws himself on a grenade to save his buddies (virtually certain death or worse). But valiant or not, it is suicide.

In my experience, suicide is just another act, no more "karmic" than anything else. Based on my own explorations, the things that really control what happens to a suicide in the afterlife are the person's state of mind, beliefs and attitudes. It may be that many who commit suicide wind up in a grim astral location (clearly, many don't), but that is driven by their state of mind, beliefs and attitudes; not the suicide. One who suicides in a mental state of confusion or delusion, or in the grip of unbearable mental or physical anguish, will be astrally placed based on those factors, not the fact of suicide.

Again, this is my experience; I don't insist upon it.
