Hello,

I'm new here and I hope i'm posting in the right section.
I'm searching for a Horror movie that is probally from the 90s,
about a man who is a serial killer, but he gets help.
He went to this medical centre for treatment, to cure this serial killer, so he can live a normal life.
The people who lived in the same town didn't accept this and said he was a murderer. So at the time when the killer was cured, the civilization hanged him in the snow. But he survived this and he became crazy again and starting to take revenge. He started killing people again.
I think he had a really white skin, long hair and glasses.

I hope somebody knows the title of this movie, because google didn't help. I saw this like 8 years ago, but I'm still searching for the title.

Sorry for my english and thanks for helping! :)
