Changing is one of the hardest things to do. The responsibility rest solely on that single person. No one can really help them.

Then arises the question do people ever honestly change? I don't think they do.
It's not being pessimistic, it's being realistic. Whatever someone tries to change about themselves, their true nature will always be there. They will always be the cocky one, mean one, know it all, etc..

Sometimes they are successful in masking it, or downplaying it, but never will it go away. That's not a bad thing either. The world needs the unique (sometimes sharp) personalities. Everyone is too caught up in trying to be perfect, and sweet. Yet the people we know the best are those who don't continually try to change something about themselves.

I'm not ignoring the people with big problems. Stories are always going around about an addict finding Christ, yada yada. But that want will always nag at them when the stess is on, and nobody is around. Life isn't fair. They shouldn't have to deal with that, but it was their decision.

I can't pass judgement whether someone has changed or not. I hope for the best, but if it doesn't happen, that's alright.
