Once I heard of a pretty silly law. I think it was in the UK. If you attempt to suicide, the government will finish you. Pretty stupid law if you ask me but as I see it the law is to help those who lives in the pain and just wants it to end.

No there is no such law in the UK nor has there ever been.
Infact attempting suicide is against the law in the UK , if your not successful it just causes a whole load of trouble involving police and mental health teams.
