I always thought I was a good person, but I guess I was wrong.
What made you realize you were a bad person?
Someone showed me what my actions have done to those around me.
It's good that your friends did that. If you're a bad person, you need to change or get help. The results from being bad end up hurting others.
I've been like this all my life and chosen to do so. I'm just going to embrace it.
I know it might seem like because you've been like this all along then you should just keep doing it, but that person showed you the results of your actions in hopes that you would change. They're trying to help you be a better person and you should want that for yourself too. Instead, you should listen to your friends' suggestions and try to do better.
