I'm going to force my friends to walk home.
Is walking home will help your friend somehow?
I just feel like my friend needs to  walk home.
If you have a way to give them a ride, it's rude to make them walk. Your friends may decide that you're not a very good friend.
Why does that make me a bad friend?
Because you have the ability to make your friend's life easier by giving them a ride but instead you are making that person walk home.
