I don't think Karofksy apologized for Kurt. I think he apologized to make himself feel better. If he had actually put any effort into chaning himself before this I might have believed him. As it is? No way. I also think you're really naive if you think all, if not most, apologies aare actually made to make the victims feel good. In my esperience they tend to be selfish.

That's MY opinion. I'm not saying anyone has to share it.
