Suicide should not be illegal, but it should also not be mandatory.
I was committed to killing myself before my 18th birthday and would have done it if any means became available. I just hated my life and didn't have anything physically wrong with me.
Then some folks talked about the Bible and I decided to prove it wrong and then do it. But the more I read, I found that God was loving people over and over again in it's pages and to Love your enemies and to do good to them. I couldn't find any fault.
Then I read how Jesus loved me by going to the cross for me for all my mistakes and all my failures. It broke my hard heart and decided to Live because of Him. Not to suicide, but to live because of His love for me. I threw away all my sins upon Him and decided to follow Him because He was worthy and to try not to follow myself anymore.
And whenever I get blue, I know to ask love from Him to enable me to do His wonderful will. This He has answered Graciously and in Abundance time and time again. Proving to me that 'Love is from God' (just as the Apostle John said).
Suicide is not the way that leads to abundant and eternal life - the Savior Jesus is. And if you ask Him into your heart humbly, you will find out that He is.

Take away the illegality of it will inevitably lead to moral and legal chaos.
