Throughout most of his sinful life, Jeffrey Dahmer was a party animal. He gave drugs away for free and had gay sex with men that he would meet at bars and night clubs. He was known for retaining his stamina long after his partners were sound asleep. Despite his homosexuality, he was also a collector of power tools, and could hold his liquor like a champ. Needless to say, Jeffrey Dahmer was extremely popular in the gay community. If they had not abandoned him for becoming a Christian late in life, I'm sure he would have led many gays to repentance and salvation.
God allowed Jeffrey Dahmer to enjoy many blessings while he was still in his sins, just like he did with King David (Jew). He was given free room and board in his grandmother's basement, and all the privacy he wanted, despite the fact that he frequently brought home drug addled men to fornicate with.
While much of what Jeffrey Dahmer did was wrong, he was not like other gays. Jeffrey Dahmer's crimes were victimless, since he only had sex with other homosexuals. He also never intentionally killed anybody. I believe the worst thing he ever did other than sodomy and drug abuse was to drill holes in his lovers' brains so that they would stay with him longer. If he had been allowed by God to marry them, then they would have been women and this would have been no problem at all according to Ephesians 5:23. But because we live in a universe where same sex marriage is wrong, these are men and therefore this is considered a crime.
Most of what Jeffrey Dahmer did really amounts to unlicensed practice of medicine, basically the same thing Jesus did throughout his ministry. The fact that some of his patients died probably had more to do with their homosexuality than his practice, but even then would have been negligent homicides or manslaughter, not premeditated murder as the heathen courts called it.
It is reassuring to know that even a dancing nancy boy like Jeffrey Dahmer can still find Jesus.
