Nichols hasn't repented, he is an evil psychopath. He has the blood of four people and countless others done irreparable harm on his hands. The concept of "repentance" is being so cheapened in this case and it sickens me. It's so easy for all these Christians to swoon over the story of his heart being opened - well, they are not the ones who have to "forgive" a murdered husband or mom or son or friend or colleague. Yes, God can forgive anyone and anything when He chooses, but He says by our fruits they will know us. He also has a Hell for people like Nichols. Let's send him there as soon as possible.
He hasn't shown himself to be a Ted Bundy yet. If he hasn't repented, time will tell.
