While I'm on my way home driving on the road, I'm planning to purposely hit a deer.
That sounds horrible! You must not kill it on purpose! Why would you do this?
I just feel like hurting something!
That sounds really dangerous! You should not take risks like that while driving, you might hurt yourself, or even someone else in the process!
I don't think I will hit a deer and it makes me feel better to think about how much pain I would cause the poor animal...
That's good, I am glad you decided not to go through with it because I think you would have heavily regretted your choice. It's very mature of you to decide not to do something so foolish and harmful.
