I'm going to tell my friend that her contracting hiv was a punishment for her sins
Do you really think she committed sins in her life?
Yes, she committed the sin of getting drunk
That's a terrible thing to say, you shouldn't make your friend feel worse after she's received bad news. You should be supportive of your friend in this trying time.
Lol, no way. I just want to watch her suffer.
If you find joy in others suffering you need help. It's not normal to feel this way when your friend is going through rough times. You should go see a therapist.
