where in the bible dose it say suicide is a sin?

Paul claims that your body is a temple of the Holy Spirit and belongs to God so isn't yours to do with as you like: "Flee fornication. Every sin that a man doeth is without the body; but he that committeth fornication sinneth against his own body. What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own? For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God's." (1 Corinthians 6:18-20). Although that refers to fornication, the principle seems to be extended to self-harm and suicide.

However, we are becoming more compassionate as a society and we'll probably make assisted suicide legal in cases of extreme suffering, subject of course to controls to protect the one being assisted. Churches and other religious organisations are opposing this, but I think it likely that charity and compassion will eventually prevail against that opposition.

Satan was originally portrayed as under the orders of God, and testing mankind under God's direction (Book of Job). And this seems to have been his function when he tempted Jesus in the desert, but perhaps starting to be presented as an enemy. The figure became demonised by early Christians, along with the deities of other peoples such as Ba’al Zebul (“Lord of Princes”, corrupted to Beelzebub “Lord of the Flies” when demonised).

The myth of the adversary/accuser probably became fearful over time. Perhaps originally fear of being found out by someone (though mythical) whose job was to do so. It might have become more comforting, by degrees, to demonise him and turn him into an enemy rather than servant of God. And in the 1st century, Greek culture was influential, so early Christians may have conflated Satan with the Greek god Pan, which explains the goat-like image often portrayed.

i suppose it would go under murder.

No, he's not one of God's angels, but was a murderer from the beginning(just like mankind).

And he did not rebel, rather God "created the waster to destroy." He's doing what God made him to do.

Suicide is a crime, but i don't think this is ending ones own life for any reason at all. It would have a criminal element to it, it is not the euthanasia of a person who is suffering horribly and just can't take it anymore, Like homocide it has a criminal element always.

For instance, if i raped someone, perhaps even several, and killed myself when i got caught to avoid the punishment for it, thats a suicide. If i have four children because i love boning and then decide i don't want to do this anymore and kill myself and abandon them to a harsh life, thats suicide.

Judas and Saul kill themselves. We are not meant to emulate them

God is in control of life.
The enemy was* one of God's angels.

satan is doing a good job screwing mankind and mankind is doing a good job getting screwed.well when you go to hell don't say we didn't warn ya

Samson committed the ancient equivalent of a suicide bombing.

Religion on the whole does enough damage in screwing mankind....or rather, mankind let's religion screw the world.
