As one of the legend singer said, in one of his memorable song "judge not" Bob Marley. Before you judge anybody judge yourself, because you too has stumbled somewhere back in your life, and added that before anybody judges him, he should make sure his hands are clean. So, I don't know how to judge you.. but, the things is that, that sins that you committed of tieding those girls hair is still hunting you, and that's the law of karma, "reap what you sow" everybody has his own sins the only thing that we can do is repent. That's all.
