The curse I cast came true.
Have you cast that curse before?
No, it was my first time casting that kind of curse.
It can be amusing to fool around with magic, but you shouldn't wish ill will on people. If someone has wronged you, then you should be direct with them or make your peace with it. Wishing ill will on others will only drag you down to their level.
They deserve it for how they've treated me.
You're going to be carrying around a lot of negative emotions if you wish ill on people. It's much healthier to forgive them or at least to move past it.
