I doubt a child molester would change but at the same time anybody could. Change for any human being is hard but possible. Conscious deliberate change goes against human nature.
The bolded is true, but whether society accepts that change is a different story. Some of us can accept change from a drug addict, wife beater, racist, rapist, molester, killer or swindler. Some of us never will.
It’s just that now we are at a point in society where we go on cyclical witch hunts. People knew what RKelly did for a while, but now that the metoo witch hunt started they want to take him out. 2 years ago it didn’t matter.
