How do you know his death isn't God's will? I respect you as a reverend and that's your job but child rapists/molesters 98% never get better. Their fail rate is sky high. I just see his suicide as reaping what you sow. If you don't get why some people are joyous over his death, it's because molesters don't get the punishment they deserve most of the time.
First, there are two aspects to God's will: the secret, and the revealed. The secret will is God's eternal counsel, which is in fact always carried out -- by God (Psalm 115:3, etc.). The revealed will is found exclusively in the Bible, tells us what we are to do or not to do, and is often violated (cf. Deuteronomy 29:29).
I know that this was not God's revealed will because God says we are not to commit murder, including the murder of ourselves (Romans 13:9).
I know that it is not God's revealed will for anyone to gloat over his murdering himself because Scripture forbids it (Proverbs 24:17-18; 1 Corinthians 13:6, etc.). The arrogant self-righteous superiority that takes joy in another's ruin is nothing commended by God (1 Peter 5:6).
Now, if you want to change the justice system, make your proposals. My questions remain unanswered. Our society tells a person the debt he owes. He pays it. Is it now our place to exact from him what we estimate as the deficit?
If so, what is the difference between that and vigilantism, mob rule, and anarchy?
Serious questions.
Dan has probably already answered this, but it seems to me that suicide could never be God's will. Suicide is the ultimate act of hopelessness, the complete and total shutting out of the Spirit. Think about it: Why did He put His only son up there on that cross? Not for some of the sins of a few chosen. For all the sins of all of us.
