I wouldn't think someone who is genuinly truly saved would kill themselves because Jesus would be your joy and you wouldn't be all screwed up to kill yourself. Second of all Killing yourself would be just breaking THOU SHALT NOT KILL which once u killed yourself you couldn't ask for forgiveness because you would be no more so I do not personally believe that someone who is a murderer could go to heaven because if u killed yourself that'd be what you were because the Bible says no Murderer shall inherite the kingdom of God along with Blasphemers, Adulterers ect..... Wide is the path to Destruction and many will follow it... and Narrow is the path to Salvation and only few find it.... Just my two cents on the ordeal...
